Answer:
-1.25, 2, 3.5
Step-by-step explanation:
(x-2)(2x-7)(4x+5)=0
(2x^2-7x-4x+14)(4x+5)=5
from now on you know that either
(2x^2-7x-4x+14)=0 or
(4x+5)=0
By solving the first eqation (2x^2-7x-4x+14)=0
you get x = 2 or 3.5
By solving the second equation (4x+5)=0
you get x = -1.25
Supplementary is 180 so 180 times 3
Answer: 13 weeks
