Answer:
6.5 hours
Step-by-step explanation:
First try to find the rate he can paint per hour
375 ÷ 3 = 125 ft^2 per hour
Then try to find how long it should take it for him to paint 812.5 sq ft
812.5 ÷ 125 = 6.5 hours
2ab - 3a = a.(2b-3)
now the same thing
let's say n=1
a.(2b-3) + n.(2b-3) = (2b-3).(a+n)

Answer:
Transformed
Step-by-step explanation:
The process of shifting the graph of the function 1 unite to the right can be obtained by subtracting 1 to the x-coordinate in the expression of the function:
The process of stretching vertically the function, would be accomplished by multiplying now the full function by "3":
the reflection over the x-axis is obtained by multiplying the full function by the constant "-1":
The answer is B 10(3+4) since 10 times 3 is 30 and 10 times 4 is 40 and this is 30+40
-24a-30. This is so because when you distribute you get numbers with like terms which you can then combine into a "simple" answer.
