For every 140 feet that Kelly rides on her bicycle, the wheels turn 20 times. About
how many times do the wheels turn in 5 miles? (1 mile = 5,280 feet)

To cover 5 miles the wheel covers 3771.42 (approx) turns.

Step-by-step explanation:

Given,

In 20 times turns wheel covers 140 feet.

1 mile = 5280 feet

To find the number of times wheels turns to cover 5 miles.

We will apply unitary method.

Now,

5 miles = 5×5280 feet = 26400 feet

140 feet covers in 20 turns

1 feet covers turns

26400 feet covers in  ×26400 turns

= 3771.42 (approx) turns

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
