For exercises 87-88, use the five steps and a polynomial equation to find the base \(b\) and height \(h\) of the triangle. The formula for the area \(A\) of a triangle is \(A=\frac{1}{2} b h\). The height \(h\) of a triangle is \(2 \mathrm{ft}\) more than the length of its base \(b\). The area of the triangle is \(60 \mathrm{ft}^{2}\).
Factor completely. Identify any prime polynomials. $$ 3 x^{18}-12 x^{9} y^{2}+12 y^{4} $$
Instead of using the zero product property, use the properties of equality to solve \(4(3 x+5)=0\).
For exercises 87-88, use the five steps and a polynomial equation to find the base \(b\) and height \(h\) of the triangle. The formula for the area \(A\) of a triangle is \(A=\frac{1}{2} b h\). The height of a triangle is \(4 \mathrm{ft}\) more than the length of its base. The area of the triangle is \(70 \mathrm{ft}^{2}\).
(a) solve. (b) check. $$ 2 w^{2}+9 w+9=0 $$
