Answer:
8+6-10+2+15-3-7-5+2-15-8+10 = 5
Step-by-step explanation:
Blake can do the work in 9 and part of work in 1 hour = 1/9
Ned can paint the same room in six hours, as well as do part of work in 1 hour = 1/6
If they do it together = 1/9+1/6=5/118, and they can do 5/18 part of work in hour = 1
So, they can do whole work in hours = 1/5/18=3.6
So if they do it together it will only take 3.6 hours.
Answer:
B
Step-by-step explanation:
I assume this should look like
V(x) = -x² + 2x - 4
W(x) = -x³ + 2x² + x + 5
when doing arithmetic operations with whole functions, we simply do these operations with the whole expressions :
V(x) × W(x) =
(-x² + 2x - 4) × (-x³ + 2x² + x + 5) =
= x⁵ - 2x⁴ - x³ - 5x² - 2x⁴ + 4x³ + 2x² + 10x + 4x³ - 8x² - 4x - 20 =
= x⁵ - 4x⁴ + 7x³ - 11x² + 6x - 20
