it will take him <u>9 weeks </u>to earn the rest of what he needs.
if he already has $105, then he will need $270 more.
Divide 270 by 30(the amount of money he gets each week) and you will get <u>9</u>.
A = 9x² + 12x
The area (A) of the rectangle is calculated as
A = height × width
= 3(3x² + 4x) ← distribute parenthesis by 3
= 9x² + 12x
