A trapezoid was broken into a triangle and rectangle.

The base of the triangle b is

5

Step-by-step explanation:

when it was a trapezoid the base was 14cm but after it got split into two piecies the base for the square was 10 but the base of the triangle is half the base of the square so it must be 5.

when studying polynomials, you often hear the terms zeros, roots, factors and x x the multiplicity of a zero is important because it tells us how the graph of the let's look at the graph of a function that has the same zeros
