Answer:

A = picture attached

B = 51 in²

Step-by-step explanation:

The picture attached is the answer for part A. You use the dimensions you already know from the first picture to fill in the net of the slice of pie.

Area of the triangle = 1/2 (base × height)

A = 1/2 (4 × 6) = 1/2 (24) = 12

The area of the triangle is 12. The top is a triangle, but the bottom is also a triangle with the same area. Therefore, the area of the two triangles combined is 24 in². Next, we have to find the area of the rectangle at the sides of the pie.

Area of rectangle = length × width

A = 5 × 2.5 = 12.5

Since there are two rectangles with the same area on both sides of the pie, we can double it and get 25 in². We still have one rectangle left, the one at the back of the pie.

A = 6 × 2.5 = 15

Add the areas altogether to get the answer.

24 + 12.5 + 15 = 51.5 in²

I hope this helps. Sorry if Part B's answer is wrong.

Hi!

Answer:

$\boxed{X=4}$

Step-by-step explanation:

You subtract by 15 both sides of an equation.

$15-3x-15=3-15$

Simplify equation.

$-3x=-12$

Then, you divide by -3 both sides of an equation.

$\frac{-3x}{-3}=\frac{-12}{-3}$

Simplify.

$12/3=4$

$\boxed{X=4}$ , which is our final answer.

Hope this helps!

Have a nice day! :)

Write an expression that represents the area of the triangle with the base 2x to the power of 2 and height 3xy ( for any triangl

madam [21]

Since:
Area of a triangle = 1/2 * base * height

2x^2 ∗ 3xy/2 6x^3y/2 = 3x^3y/1

3x^3y/1

Therefore, the expression that represents the area of the triangle is 3x^3y/1.

I hope my answer has come to your help. Thank you for posting your question here in Brainly.

Answer:

25.047 or roughly 25.

Step-by-step explanation:

I solved it wrong the first time then i double check with wolframalpha and got the correct number.

We know that the area of the tile is 18 $\sqrt{3}$ and it makes a triangle, we also know the base and height. In this case the base is 2 $\sqrt{3}^{x/12}$ and the height is also given which is $\sqrt{3}^{\frac{x}{6} }$ .
