It would be proportional to the base of the first triangle. Find it by setting up a proportion:

18/22 = 12/x

Cross multiply and solve for x.

18x = 264

x = about 14.67 cm

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials
