Help me (i will give you 10 points)

First I found the area of the overall shape:

(x+8)(x+8)

I got:

x^2 + 16x + 64

Then I found the area of the inside shape:

2x * 2x

I got:  4x^2

Then I subtracted the inside shape from the total shape:

and I got:

-3x^2 + 16x + 64

The area of the shaded part is D sq unit.

Step-by-step explanation:

Given,

The length of outer square = x+8 unit

The length of inner square = 2x unit

To find the area of the shaded part

Formula

The area of a square with each side a will be sq unit

Now,

The area of the outer square = sq unit

The area of the inner square = sq unit

Hence, the area of the shaded part =

- sq unit =

sq unit

step-by-step explanation:

answer: the equation matches the regression
