Answer:
-14400
Step-by-step explanation:
6/2 (-75*4³)=-14400
4³=64
6/2(-75*64)
6/2(-4800)
3(-4800)=-14400
Equation 1: x + y = 40 ; therefore y = 40 - x
Equation 2: 25x + 15y = 900
Find x first:
25x + 15 (40 - x) = 900
25x + 600 - 15x = 900
10x = 900 - 600
x = 300÷10
x = 30 hours Chris needs to spend for tutoring job
y = 40 - 30
y = 10 hours Chris needs to spend for referencing job

Equal because these numbers are of the same value
p = 2(l+w)
divide by 2
p/2 = l+w
subtract l from both sides
p/2 - l = 2
