Answer:
9x² - 24x + 16
Step-by-step explanation:
Formula for the area of the square base = s²
Where,
s = side length = 3x - 4
Therefore:
Area of the base = (3x - 4)²
Expand
(3x - 4)(3x - 4)
3x(3x - 4) -4(3x - 4)
Apply the distributive property
9x² - 12x - 12x + 16
Add like terms
9x² - 24x + 16
Area of the base in standard form = 9x² - 24x + 16
Answer:
9x^2 -24x +16 units^2
Step-by-step explanation:
(3x-4)^2 = 9x^2 -24x +16
