12. Acme movers charges a one-time fee of \( \$ 45 \) plus \( \$ 40 \) per hour to move household items across town. Hank's Movers charges \( \$ 55 \) per hour. Find the number of hours required for the moving companies to have equal total costs.

The function below has at least one Rational zERO. use this fact to find all zeros of the function \( f(x)=3 x^{3}-2 x^{2}-7 x-2 \) If there is more than zero, seperate them with commas. Write exact values, not decimal approximations.

What is one of the factors of \( 2 x^{2}+5 x-3 \) ? A \( 2 x-3 \) B \( 2 x+1 \) C \( 2 x+3 \) D \( 2 x-1 \)

19. Give the vertex form and factored form of \( f(x)=x^{2}-12 x+35 \). What specific information doe: each form provide?

solve for \( x \) \( \log _{2}(5 x-7)=1 \)

Simplify: \( (3 x+5)^{2} ? \) A \( 9 x^{2}+25 \) B \( 6 x^{2}+10 \) C \( 9 x^{2}+30 x+25 \) D \( 9 x^{2}+15 x+25 \)
