Write a polynomial in standard form that represents the area of the shaded region

Step-by-step explanation:

The formula for Area of a square is

Due to this we figure out our first equation:

Then we have the  inner part and that equation is (second equation):

Since we have our 2 equations, the operation between them is subraction since we don't want the inner part. So the final equation or the answer

Hope this helps! :D

x^2-3x+36

Step-by-step explanation:

You just simplify (x+1)^(2)-(x-7)(5) and that's what you get. I'm doing the hw right now and it checked as right so trust me bestie :)

3 3 6, because in every triangle the longer side is always shorter than the sum of the other two

363 square inches

step-by-step explanation:

surface area of a pyramid is b + 1/2ph

b is the area of the base: 11 x 11 = 121

p is the perimeter of the base: 11 + 11 + 11 + 11 = 44

h is the height of the pyramid: 11

121 + 1/2(44)(11)

121 + 242

363
