Step-by-step explanation:
A) 3x²c² + 5xc² - 2c²
Factor c² from all terms in the expression.
c²(3x² + 5x - 2)
Factor 3x² + 5x - 2
c²(3x-1)(x+2)
B) x² + 6x + 9
x² + 3x + 3x + 9
Factor common terms.
x(x+3)+3(x+3)
Take x+3 common.
(x+3)(x+3)
C) x² - 9
x² -3²
Apply formula : a² - b² = (a+b)(a-b)
(x+3)(x-3)
Independent variable: The number of houses Harold sells
Dependent Variable: The amount of money Harold earns
Function: f(x)=250,000(x)
x represents how many houses Harold sells, and f represents how much money Harold earns.
Now, let's solve the problem.
f(x)=250,000(9)
f(x)=2,250,000
Harold earns $2,250,000
