Aparallelogram has an area of 4x^2 + 7x - 15. the base of the parallelogram is x + 3. what is the height of the parallelogram? a. write the formula for the area of a parallelogram. b. explain how factoring the trinomial solve the problem.

A. Opposite sides are equal in length and opposite angles are equal in measure. To find the area of a parallelogram, multiply the base by the height. The formula is: A = B * H where B is the base, H is the height, and * means multiply.

b. A trinomial is a polynomial with 3 terms.. This page will focus on quadratic trinomials. The degree of a quadratic trinomial must be '2'. In other words, there must be an exponent of '2' and that exponent be the greatest exponent.

ummm...I hope it helps you!!

Maybe the answer is 20mm. all i really did was just multiply, which is obvious.
