Answer:
x= -6
Step-by-step explanation:
first you want to get rid of the 4 so on both sides you subtract 4
4-x²=-32
-4 -4 that will then make the problem
-x²= -36 to get rid of the square you must do the opposite, square root ([tex]\sqrt{36}[/tex]) so it will get rid of the ²
-x= 6 then you have to get rid of the neggative on x so you will add a negative to 6
x=-6

What is the x value for the solution -x+2y=6
6y =x+18
For the given set of equations, x = 0 and y = 3.
Step-by-step explanation:
Step 1:
From the question,
[tex]-x + 2y = 6[/tex], take this as equation 1,
[tex]6y =x+18, x - 6y = -18[/tex], take this as equation 2.
Step 2:
When we add equation 1 and equation 2, the x variable is canceled out and y can be calculated.
[tex]-4y = -12, y = \frac{-12}{-4}, y = 3.[/tex]
Step 3:
Substituting this value of y in any of the previous equations we will get x's value.
Here this value of y i.e y = 3 is substituted in equation 1.
[tex]-x + 6 = 6, -x = 6 -6, -x=0, x=0.[/tex]
So we have x = 0 and y = 3.

Step-by-step explanation:
For a game, Tony has a rectangle drawn on a piece of paper that has an area of 18 in.^2. What should he do to the dimensions in order to have a similar rectangle that's area is only 2 in.^2?
options:
Divide them by nine.
Divide them by six.
Divide them by three.
Multiply them by three.
We have to divide the dimensions by 9 to get a similar rectangle that's area is only 2 in.^2
Solution:
Given that,
For a game, Tony has a rectangle drawn on a piece of paper that has an area of 18 in.^2
In order to have a similar rectangle that's area is only 2 in.^2
Thus, we need to find the scale factor
Let "c" be the scale factor
Let "x" be the area of original rectangle
Let "y" be the area of dilated rectangle
Therefore,
[tex]c = \frac{y}{x}\\\\c = \frac{2}{18}\\\\c = \frac{1}{9}[/tex]
Therefore, we have to divide the dimensions by 9 to get a similar rectangle that's area is only 2 in.^2

Plzz help fast /The volume of the prism
Answer:
1716 m^3
Step-by-step explanation:
We can find the volume of a triangular prism by thinking about it like this - it's half of a rectangular prism. It's just be cut diagonally. So we can imagine that the measurements of the potential rectangular prism are 6m x 26 m x 22m.
Volume of rectangular prism:
6*26*22 = 3432
Volume of triangular prism:
1/2 of rectangular prism - 3432/2 = 1216
Answer:
Step-by-step explanation:
Volume of the prism is calculated by base and height
V= bh
From the figure, base = 6m
Where height = 26m
V = 26m x 6m
= 156m^2

Maria put trim around a banner that is the shape of a triangle. Each side is 22 inches long. Maria has 1/2foot of trim left. What was the length of the trim when she started? Write your answer in yards
Maria had 2 yards of trim when she started.
Step-by-step explanation:
Step 1:
All of the sides of the triangle is 22 inches long each.
The total length of the sides of the triangle [tex]= 3(22) = 66.[/tex]
So the total length of the trim for the banner is 66 inches long.
If Maria still has [tex]\frac{1}{2}[/tex] a foot of trim left, she had 6 inches of the trim left.
The length of the trim when she started[tex]=66 +6 = 72[/tex] inches.
Step 2:
Now we need to convert the 72 inches into yards.
We have 1 inch = 0.0277778 yards.
So 72 inches [tex]= 0.0277778(72) = 2.[/tex]
So Maria had 2 yards of trim when she started.
A basketball team scored 82 points
in a game. The players made no free
throws and the number of two-point
ifield goals was 2 more than 5 times the
number of three-point Shots.
How many of each Shot did they make
Number of 3-point shots are 13 and number of 2-point shots are 69
Step-by-step explanation:
Step 1: Let the number of 3-point shots be x, then the number of 2-point shots will be 5x + 2. Total points = 82. Form an equation to find x.⇒ 82 = x + 5x + 2 = 6x + 2
⇒ 80 = 6x
∴ x = 80/6 = 13.33 ≈ 13
∴ 5x + 2 = 66.67 + 2 = 68.67 ≈ 69

In the figure below, ABO and GOF are right triangles. How would you represent the area of the shaded region?
1. r^2 (π-1)
2. r^2 (π+1)
2. r^2 (π-1/2)
3. r^2 (1-π)
Answer:
option 1
Step-by-step explanation:
The shaded area is area of circle - area of 2 congruent triangles
area of circle = πr²
Note that the base and height of both triangles is the radius
Area o triangle = [tex]\frac{1}{2}[/tex] × r × r = [tex]\frac{1}{2}[/tex]r²
area of 2 triangles = 2 × [tex]\frac{1}{2}[/tex] × r² = r²
area of shaded region = πr² - r² = r²(π - 1) → (1)
To represent the area of the shaded region in the figure, use the expression "r² (π+1)" as it closely approximates the calculation for the shaded area.
In the figure described, ABO and GOF are right triangles, and there's a shaded region within these triangles. To represent the area of the shaded region, we can consider the difference between the areas of the larger triangles ABO and GOF and the smaller semicircles centered at O within each triangle.
The area of a triangle is given by (1/2) × base × height, and the area of a circle is πr², where "r" is the radius.
Calculate the area of ABO: (1/2) × AB × AO
Calculate the area of GOF: (1/2) × GO × GF
Calculate the area of one semicircle: (1/2) × πr²
Now, to find the area of the shaded region, subtract the sum of the areas of the two semicircles from the sum of the areas of the two triangles:
Shaded Area = (ABO - πr²) + (GOF - πr²)
So, the representation for the area of the shaded region is:
Shaded Area = (1/2) × AB × AO + (1/2) × GO × GF - πr²
Therefore, option 2, "r² (π+1)," is the closest representation of the area of the shaded region.

82 children had to learn the one line of fun song. The fun song has 47 lines. How many lines did they learn altogether
Answer:
3,854
Step-by-step explanation:
There’s 82 kids each learned 47 lines you would multiply
The children learned a total of 3854 lines of the song. This is found by multiplying the number of children by the number of lines in the song.
Explanation:This problem involves simple multiplication. Since each child needs to learn one line of the song, and the fun song has 47 lines, to find the total number of lines the children learned altogether, you simply multiply the number of children by the number of lines in the song. Therefore, 82 (number of children) x 47 (number of lines in the song) equals 3854. So, the children learned 3854 lines in total.

Answer: 1) 1 1/2, 2 1/4, and 4
Step-by-step explanation: 1) We know that the equation would be the cups of flour being multiplied by the batches. Like, 5 times 3/4 would equal 15/4 which would simplify to 3 3/4.
So, to find the first missing number, we do 2 x 3/4, which equals 6/4( 1 1/2).
The next missing number would be 3, because we're going in order-- like 1, 2, 3, 4. So we do 3 x 3/4.
We then don't have a number for batches this time. So we still do, 3/4 x 3 but this time we cross out both the 3 on the top and we're left with 4, our answer.
The equation for this is 3/4 x b. (Did this help..?)
