Step-by-step explanation:

We can start by finding values of the functions at x=1 and x=2.

  f(1) = 3(1) +1 = 4

  f(2) = 3(2) +1 = 7

  g(1) = 4(1) -2 = 2

  g(2) = 4(2) -2 = 6

__

(f +g)(2) = f(2) + g(2) = 7 +6 = 13

__

(2f +g)(1) = 2f(1) +g(1) = 2(4) +2 = 10

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft

they would have to work 32 hours.
