10 in = A of triangle so 35+10 = 45
It would be d. none of the above
this would mean $360 earned in 30 hours
65+55=120
120÷2=60
So, it take them 60mins if they worked together.
Answer:
{-5/4, 8}
Step-by-step explanation:
We are given (4u + 5)(8 - u) = 0. Solve for u by setting each of the factors (4u + 5) and (8 - u) equal to zero and solving each of the resulting equations:
4u + 5 = 0 leads to u = -5/4, and
8 - u = 0 leads to u = 8.
The solutions are {-5/4, 8}
