Expression: [tex]\((x - 3)(x + 5)\)[/tex]. If original is 10 × 10, new is 105 sq ft. New is 5 sq ft larger.
1. **Expression representing the two binomials for the area of Talia's new bedroom:**
Let [tex]\( x \)[/tex] represent the original length of the square bedroom.
The original bedroom's dimensions: [tex]\( x \times x \)[/tex]
The new bedroom's dimensions: [tex]\( (x - 3) \times (x + 5) \)[/tex]
So, the expression representing the two binomials would be: [tex]\((x - 3)(x + 5)\)[/tex]
2. **Finding the difference in size between old and new bedrooms:**
If the original bedroom measured 10 feet by 10 feet, then [tex]\( x = 10 \)[/tex] (since it's a square).
Substituting into the expression: [tex]\( (10 - 3)(10 + 5) = (7)(15) = 105 \)[/tex] square feet.
So, the new bedroom's area is 105 square feet.
The original bedroom's area is [tex]\( 10 \times 10 = 100 \)[/tex] square feet.
The difference is: [tex]\( 105 - 100 = 5 \)[/tex] square feet.
Therefore, her new bedroom will be 5 square feet larger than her old bedroom.
The complete question is here:
Talia has a square bedroom. Her family is moving and her bedroom in her new apartment will be 3 feet shorter in one direction and 5 feet longer in the other direction. Write an expression that represents the two binomials you would multiply together to find the area of Talia's new bedroom.
2nd Part
If Talia's old bedroom measured 10 feet by 10 feet, how much larger or smaller will her new bedroom be?

B. The range is positive real numbers (y> 0).
O
C. The domain is all real numbers.
O
D. It has a slope of 1.
The characteristic of the linear parent function that is not true is that the range is positive real numbers (y > 0).
Explanation:The correct answer is B. The characteristic of the linear parent function that is not true is that the range is positive real numbers (y > 0).
A linear parent function is represented by the equation y = x and passes through the origin (0,0). Its domain is all real numbers (-∞, ∞) and its range is also all real numbers (-∞, ∞).
A linear function with a slope of 1 is represented by the equation y = x and is a straight line that passes through every point on the graph that has the same x and y value.

Option B 'The range is positive real numbers (y>0)' is not a characteristic of the linear parent function. The function y=x, known as the linear parent function, has its range as all real numbers, not just positive.
Explanation:The characteristic of the linear parent function, which is not accurate, is: 'The range is positive real numbers (y>0)'.
The linear parent function is y = x, which indeed meets the criteria of the remaining options. It goes through the origin (0,0), its domain covers all real numbers, as x can be any real number, and it has a slope of 1 throughout. However, its range is not only positive real numbers (y>0). The range of the linear parent function actually includes all real numbers because y (the output) can take any real value, both positive and negative, not just positive.

Australia is approximately 3,000,000 square
miles in area. Sand dunes cover 40% of the land.
How much of Australia is
covered by sand dunes?
Answer:
1,200,000 square miles
Step-by-step explanation:
Given data:
Total land = 3 000 000
40% is covered by sand dunes
Land covered by sand dunes is 40% of the total area therefore
Land covered by sand dunes=(40/100) * 3000000
Land covered by sand dunes= 0.4 * 3000000
Land covered by sand dunes= 1 200 000
Final answer:
Approximately 1,200,000 square miles of Australia are covered by sand dunes, which is 40% of Australia's total area of about 3,000,000 square miles.
Explanation:
The student has asked how much of Australia is covered by sand dunes given that Australia's area is approximately 3,000,000 square miles and sand dunes cover 40% of the land.
To calculate the area covered by sand dunes, we apply the percentage to Australia's total area:
Convert the percentage into decimal form: 40% = 0.40.
Multiply the total area of Australia by the decimal: 3,000,000 square miles × 0.40.
The result gives us the area covered by sand dunes: 1,200,000 square miles.
Therefore, sand dunes cover about 1,200,000 square miles of Australia.

difference in the monthly interest owed during year 1 and year 2?
O a) $10.80
Ob) $15.66
O c) $22.50
O d) $34.50
Answer:
c) $22.50
Explanation:
1. Calculate the monthly interest owed during year 1
Interest for first year: 8%The monthly rate is the yearly rate divided by 12: 8% / 12 = 0.08/12The monthly interest owed is the monthly rate times the balance: (0.08/12)×$1,800 = $12.002. Calculate the monthly interest owed during year 2
Interest for second year: 23%The montly rate is the yearly rate divided by 12: 23% / 12 = 0.23/12The monthly interest owed is the monthly rate times the balance: (0.23/12)×$1,800 = $34.50
3. Calculate the difference
Difference in the monthly interest owed during year 1 and year 2 = $34.50 - $12.00 = $22.50Hence, the answer is the option c) $22.50
What is the parallel line to y=-4x-5 and passes the point (-2,6)
Answer:
y = - 4x - 2 is the required equation of the line.
Step-by-step explanation:
Equation of two parallel lines differ only by a constant.
If the equation of a line is [tex]$ ax + by + l = 0 $[/tex] then the equation of the line parallel to it is given by [tex]$ ax + by + k = 0 $[/tex].
Note that only the constants differ in both the equations.
The given equation is: y = - 4x - 2
This is equivalent to 4x + y + 2 = 0.
Therefore, the equation of the line parallel to the given line will be:
4x + y + k = 0.
We are also given the point which passes through the line. We can substitute it to determine the value of 'k'.
Substituting (- 2, 6), we get:
4(-2) + 6 + k = 0
⇒ - 8 + 6 + k = 0
⇒ k = 2
Hence, the equation of the required line is: y = - 4x - 2
A container holds sugar shape of a cylinder that radius of the containers 3 inches in the height of the container is 10.5 inches which measurement is closest to the volume of the container cubic inches
Answer:94.5pie
Step-by-step explanation:
Final answer:
To calculate the volume of a cylindrical sugar container with a radius of 3 inches and a height of 10.5 inches, use the formula V = πr²h, which yields approximately 296.78 cubic inches.
Explanation:
The question asks for the volume of the container that has the shape of a cylinder. The given dimensions are a radius of 3 inches and a height of 10.5 inches. To find the volume of a cylinder, we use the formula:
V = πr²h
Where V is the volume, π (pi) is a constant approximately equal to 3.14159, r is the radius, and h is the height of the cylinder.
We calculate the volume as follows:
V = π × (3 inches)² × 10.5 inches
V = π × 9 in² × 10.5 in
V = π × 94.5 in³
V ≈ 296.78 in³
Thus, the volume of the cylinder is approximately 296.78 cubic inches

Answer:
MN = 10
Step-by-step explanation:
To find the length of a line segment or the straight distance between two points, use the formula [tex]L = \sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}[/tex] , where you can substitute two points, which would be (x₁ , y₁) and (x₂ , y₂). "L" stands for length.
Choose point 1 and point 2:
Point 1: M (2, -3) x₁ = 2 y₁ = -3
Point 2: N (8, 5) x₂ = 8 y₂ = 5
Substitute the values for the variables:
[tex]L = \sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}[/tex]
[tex]L = \sqrt{(8-2)^{2}+(5-(-3))^{2}}[/tex] Solve inside each bracket first by adding
[tex]MN = \sqrt{(6)^{2}+(8)^{2}}[/tex] Square each number
[tex]MN = \sqrt{36+64}[/tex] Add the numbers
[tex]MN = \sqrt{100}[/tex] Find the square root
[tex]MN = 10[/tex] Length of the line segment
Therefore the length of the line segment MN is 10.
The sum of two numbers is a hundred one number is at least 16 more than the other number. What are the numbers? Please help
Answer:
42 and 58
Step-by-step explanation:
Let the two numbers be represented by A And B
A + B = 100
A = B + 16
Substitute B + 16 in place of A in equation 1
We have,
B + 16 + B = 100
It can also be written as
B + B + 16 = 100
2B + 16 = 100
Subtract 16 from both sides
2B + 16 - 16 = 100 - 16
2B = 84
Divide both sides by 2
2B/2 = 84/2
B = 42
Now substitute 42 for B in any of the equations to get A.
Using equation 1
A + B = 100
A + 42 = 100
Subtract 42 from both sides
A + 42 - 42 = 100 - 42
A = 58
Therefore the two numbers are 42 and 58
