Answer:
= 3*3*3 or 27
= 4*4*4 or 64
= 3*3*3*3 or 81
Step-by-step explanation:
Hope this helps! :)
It's +31.
if there's a minus next to a bracket you have to turn every operator the opposite inside that bracket
-(-31) = +31
200
Let width = x
Let length = 2x
Let’s area = a
x+2x+x+2x=60
Combine the terms
6x = 60
Divide both sides by 6
x = 10
Width = 10
Length = 2*10 = 20
Area = 10*20 = 200
You need to find out how many problems Carl can do in a minute (unit rate), which is 20/55 or .36363636363. If you multiply it by 75 mins, you get 27.27, so the answer would be 27.
