Sam created a video that was originally 77 minutes long, but he ended up cutting it
by 20%. How long was his video after he cut it?

61.6 minutes

Step-by-step explanation: First you have to turn 20% into a decimal. 20% as a decimal is 0.2. Then, you have to multiply 77 and 0.2 which gives you 15.4. Lastly, you subtract 15.4 from 77. This gives you your answer-61.6 minutes.

step-by-step explanation:

it will be a cylinder. with a diameter of 8 and 4 single pieces high

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
