F(x) = 3x + 5 g(x) = 4x2 – 2
h(x) = x2 – 3x + 1

Find f(x) = g(x) – h(x).

A.-5x² +6

B.5x² + 6x + 4

C.-5x2 + 6x + 6

D.5x² + 4

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9

step-by-step explanation:

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y
