hi,

you must replace x by the number between parenthese.

I show you with the first one and let you do the second one

p(x) = 11x^5 -11x^4 - 5x^2 +15x-8

p(-4)  =   11 (-4)^5 - 11 (-4)^4 -5(-4)² +15(-4) -8

p(-4) =     11  ( -1024- 256) - 5*16 -60-8

p(-4) =   11 ( -1280) -80-60-8

p(-4)   =    - 14080 - 148

p(-4) =   - 14 228

Kimberly rides her bicycle from her home to school at an average rate of 12 mph if it takes her 20 minutes to get to school how
Thepotemich [5.8K]

Kimberly's home is 6.6 miles away from her school.

Step-by-step explanation:

The formula for speed will be used to calculate distance between home and school of Kimberly.

The formula for speed is:

s=\frac{d}{t}

Here

d is distance

s is speed and

t is time

Given:

Speed=s=12\ mph\\Time=t=20\ min\\\\We\ have\ to\ convert\ the\ time\ into\ hours\ for\ same\ unit\\t=20\ min = \frac{20}{60} = 0.33\ hour\\Now,\\20=\frac{d}{0.33}\\20*0.33=d\\d=6.6\ miles

Kimberly's home is 6.6 miles away from her school.
