Find the area of a square with a side length 2x2 - 9.

A = 4x⁴ - 38x² + 81

Step-by-step explanation:

The formula for the area of a square is side X side, or side squared, or A = s².

Substitute the equation of a side into the formula.

A = s²

A = (2x² - 9)²

A = (2x² - 9)(2x² - 9)    <=distribute over brackets

A = 4x⁴ - 18x² - 18x² + 81   <= collect the like terms - 18x² and - 18x²

A = 4x⁴ - 38x² + 81   <= final equation for area

2.) 14x9= 126, so divide that by 3. Ryan can make 42 small bags of popcorn
