Answer:

4a² + 4ab + b² units²

Step-by-step explanation:

Area of a square = Length²

ER is a length of the square

ER = (2a + b)

Area of a square = (2a + b)² = (2a + b)(2a + b) = (2a)(2a) + (2a)(b) + (2a)(b) + (b)(b) = 4a² + 4ab + b²

The area of the square OSER = [tex]4a^{2}+4ab+b^{2}[/tex] sq unit

Step-by-step explanation:

Given,

Length of each side(ER) = (2a+b) unit

To find the area of the square OSER.

Formula

The area of a square with each side a unit is [tex]a^{2}[/tex] sq unit

[tex](a+b)^{2}= a^{2} +b^{2} +2ab[/tex]

Now,

The area of the square OSER = [tex](2a+b)^{2}[/tex] sq unit

= [tex]4a^{2}+4ab+b^{2}[/tex] sq unit [ by using the formula of ([tex]a+b)^{2}[/tex]]

Answer:

Step-by-step explanation:

x + y = 9

x = 9 - y

2x - y = 0

2(9 - y) - y = 0

18 - 2y - y = 0

-3y = -18

y = 6

x = 9 - y

x = 9 - 6

x = 3

The value of x and y are 3 and 3 respectively in the given system of equations.

A system of equations is a set of two or further equations that own an identical set of unknowns. The thing of solving a system of equations is to determine the values for the unknowns that quench all of the equations in the system.

It is given that the system of equations is,

2x - y = 0

x + y = 9

Now, from the first equation, we get

y = 2x

On putting the above value of y in the second equation, we get

x + 2x = 9,

3x = 9,

x = [tex]\frac{9}{3}[/tex]

x = 3.

Now putting this value of x in the first equation, we get

2 [tex]\times[/tex] 3 + y = 9

6 + y = 9

y = 9 - 6

y = 3.

So, x = 3 and y = 3 in the above system of equations.

Answer:

Step-by-step explanation:

Given that,

x^8/x^a=x²

Applying indices

Division rule a^m ÷ a^n = a^(m-n)

Then,

x^8/x^a=x²

x^(8-a)=x²

For this to be equal means that, the power are equals since they have the same base

Then, 8-a=2

8+2=a

So, a=10

Taking the second equation

(x^6)^b=x¹²

Using indices again

x^(6b)=x¹²

Also, for this to be equal

6b=12

Then, b=12/6

b=2

Then, b=2 and =10

We need to find b-a.

b-a=2-10=-8

Then, the answer to b-a is -8

midpoint formula

Length of a line segment with endpoints (x1, y1) and (x2, y2) is given by,

Midpoint= [(x2 + x1)/2 , (y2 + y1)/2]

To find the midpoint of EC

Let   (x1, y1) = E(2t, 0) and  (x2, y2) = C(2p, 2r)

Midpoint = [(2t + 2p)/2 , (0 + 2r)/2]

= (2(t + p)/2 , 2r/2)

= (t + p, r)

Therefore midpoint of EC = (t + p, r)

Final answer:

The length of the rectangle with a perimeter of 60 inches and a width of 12 inches is 18 inches, calculated using the perimeter formula for rectangles and solving for the length.

Explanation:

The question asks us to find the length of a rectangle given its perimeter and width. To solve this, we use the formula for the perimeter of a rectangle, which is P = 2l + 2w, where P is the perimeter, l is the length, and w is the width. In this case, we have P = 60 inches and w = 12 inches.

So, substituting the given values into the formula, we get:

60 = 2l + 2(12)

First, calculate the double of the width:

2(12) = 24 inches

Now, subtract this value from the total perimeter to find the double of the length:

60 - 24 = 36 inches

Finally, divide by 2 to find the length of the rectangle:

36 / 2 = 18 inches

Therefore, option B, 18 inches, is the correct answer for the length of the rectangle.

Answer:

x > -3/14

Step-by-step explanation:

Step 1:  Subtract 2x from both sides

16x - 2x > 2x - 3 - 2x

14x > -3

Step 2:  Divide both sides by 14

14x / 14 > -3 / 14

x > -3/14

Answer:  x > -3/14

C. Coordinates of D' (-6,3)

Step-by-step explanation:

When any figure is rotated 180° in the counterclockwise direction, then the coordinates of the vertices is changed into its opposite sign.

(x, y) → (-x, -y)

The coordinates of the vertices of quadrilateral ABCD is changed when it is rotated 180 degrees counterclockwise about the origin as,

A (7,-7) → A'(-7,7)

B (4,-10) → B' (-4,10)

C (1.5, -2.5) → C' (-1.5, 2.5)

D (6, -3) → D'(-6,3)

So the coordinates of D' will be (-6,3)

Final answer:

To find the approximate value of land purchased for $30,000 in 1960 with a 5% annual increase by 2011, we use the compound interest formula which results in an approximate value of $447,187.25.

Explanation:

To determine the approximate value of land in the year 2011, which was purchased for $30,000 in 1960 with an average annual increase of 5%, we will use the formula for compound interest. This situation can be treated as a compound interest problem where the initial principal is the initial land value, the rate is the annual increase, and the time is the number of years the land has appreciated.

The compound interest formula is [tex]A = P(1 + r/n)^(nt),[/tex] where A is the future value of the investment/loan, including interest, P is the principal investment amount (initial value of land), r is the annual interest rate (annual increase in value), n is the number of times that interest is compounded per year, and t is the time the money is invested or borrowed for, in years.

In this scenario, P is $30,000, r is 0.05 (5% expressed as a decimal), n is 1 since we are compounding annually, and t is 51 (2011 - 1960).

Therefore,

[tex]A = 30,000(1 + 0.05/1)^(1*51).[/tex]

Carrying out the calculation gives us the approximate value of the land in 2011.

[tex]A = 30,000(1.05)^51[/tex]
Approximate value of the land in 2011 = $447,187.25

B

for a square diagonal is found by using pythagoras theorem.

(30)²+30²=900+900=1800≠45²

The best describes the shape of the baseball field would be; B Not square (30)² + 30² ≠45².

If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:

|AC|^2 = |AB|^2 + |BC|^2    

where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).

Giselle is building a small baseball infield for her brother.

The infield should be in the shape of a square.

Each side of the infield, between bases, measures 30 feet.

The distance between home plate and second base, as shown in the picture, is 45 feet.

A square diagonal can be calculated by using the Pythagoras theorem.

|AC|^2 = |AB|^2 + |BC|^2    

= (30)² + 30²

= 900 + 900

= 1800
