Question

A rectangle has a height of 7 and a width of 2x^2 - 3.


Please help

Answer 1

14x² - 21

Explanation:

In order to expand the expression, you simply need to multiply 7 by 2x², then by -3.

2x² × 7 = 14x²

-3 × 7 = -21

Therefore, the area of the entire rectangle is 14x² - 21 (you will not need to solve for x, as there is no way to do that without knowing the area first).
