Answer: 3/2a3
I can't properly write the answer sorry but it's the last one.
The length of the base 3 times the width. And we need to express the surface. I'm assuming the surface of the base. So, to get the area of the base, multiply w * l.
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Point Form:
x= 1, y= -4
