.What is the speed of a jet plane that travels 528 meters in 4 seconds?

132 m/s

Explanation:

Average speed is defined as the distance traveled divided by the time of travel, so in your case

v

=

528 m

4 s

=

132 m/s

the radius is 2 times the diameter.

step-by-step explanation:

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
