Q:
# So if the length of one side of a square field is represented by the expression 3-7x .Write an expression for the perimeter of the field expressed as a sum.

Accepted Solution

A:

So plugging in what we are given

3-7x

| |

3-7x|___|3-7x

3-7x

To find the perimeter you add up all the sides

so

(3-7x) + (3-7x) + (3-7x) + (3-7x) = P

then we combine like terms

3 + 3 + 3 + 3 -7x -7x -7x -7x = P

9 + 9 -14x -14x = P

- 28x + 18 = P

Hope this helps :)
