The area of a trapezoid is A =1/2h(b+B) Solve the formula for the height h.

Let's solve for h ~

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

4x and 6y

im not sure though
