Ava is building a rectangular sandbox a model of the sandbox dimensions are shown which expression represents the perimeter of ava’s sandbox

Option E:

Step-by-step explanation:

You need to remember that the perimeter of a rectangle can be calculated with the following formula:

Where "l" is the lenght of the rectangle and "w" is the width of the rectangle.

In this case, you can identify from the figure that:

So, knonwing this, you can write the following expression to represent the perimeter of the rectangle:

The final step is to simplify the expression. Then you get:

This matches with the Option E.

answer: 75°

step-by-step explanation:

∠esk is the supplement of ∠edk, so is 100°. ∠esd = 1/2·arc ed, so is 25°.

since ∠esk = ∠esd + ∠dsk

you have 100° = 25° + ∠dsk . .

fill in known values 75° = ∠dsk . . . . .

subtract 25°

step-by-step explanation:

the answer to this is a. a^2 + b^2 = c^2
