Simplify ( 1/2A + 1/2B )^2

Notice that both A and B are multiplied by (1/2).

Thus, the given expression can be re-written as [(1/2)(A+B)]^2.

Square the (1/2) and the (A+B) separately, and then multiply together the resulting squares:

(1/4)(A^2 + 2AB + B^2)

Thus, the given expression can be re-written as [(1/2)(A+B)]^2.

Square the (1/2) and the (A+B) separately, and then multiply together the resulting squares:

(1/4)(A^2 + 2AB + B^2)

Find the length of the side marked x. the perimeter is 12 feet.

I might be wrong but I think it is 93 cause each sides of the triangle equals 31.

This seems like it is a Pythagorean theorem problem. Using the height and half the base for a^2 + b^2 = c^2 so 2^2+3^2 = c[x]^2. the answer is square root of 13.
