Base = Height, Let them be x.
Solve quadratic equation:
x=6, x=-2(rejected because base and height is positive)
6x6/2 =18
D. no definite shape or definite volume
A linear equation in two variables doesn't involve any power higher than one for either variable. It has the general form Ax + By + C = 0, where A, B and C are constants. It's possible to simplify this to y = mx + b, where m = ( −A / B) and b is the value of y when x = 0. A quadratic equation, on the other hand, involves one of the variables raised to the second power. It has the general form y = ax2 + bx + c. Apart from the adding complexity of solving a quadratic equation compared to a linear one, the two equations produce different types of graphs.
D because (x-5)*x^2
I really hope this helps
