Answer:
I can't solve this completely for you, but I'll help you figure it out.
Step-by-step explanation:
All you need to do is choose a number to plug in for x, I'd start with zero and work my way up. Do this for all equations to solve for solutions to your problem.
Answer:
x + 3
Step-by-step explanation:
1. The area of a rectangle is length times width.
A = LW
2. Solve for the width by dividing both sides of the equation by the length:
W = A / L
3, Plug in the expressions for A and L:
W = (3x² + 9x) / 3x
W = (3x² / 3x) + (9x / 3x)
W = x + 3
