Kyla makes a triangular school pennant. the area of the triangle is 180 square inches. the base of the pennant is z inches long. the height is 6 inches longer than twice the base length. what is the hieght of the pendant if a=1/2(b)(h)

We can represent the base as z and the height as 2z+6. We are going to use the formula A=1/2*b*h and solve for z
180=1/2*z*(2z+6)
360=2z^2+6z 
0=2z^2+6z-360
0=2(z^2+3z-180)
0=(z+15)(z-12)
So z=-15 and 12 but it must be positive so then the base is equal to 12

When we plug this into 2z+6 we get 30 for the height
2(12)+6=30

Hope this helps
