Since that is only one set of numbers, you would have to start on the origin, then move right on the x-axis twice because the first number is 2, and stay there for the other half of the equation since the other number is 0.

Answer: Choice F) 1</h3>
=============================================
Explanation:
x^2+8x+7 factors to (x+1)(x+7)
x^2+4x-21 factors to (x-3)(x+7)
Therefore, the numerator (x^2+8x+7)(x-3) updates to (x+1)(x+7)(x-3)
The denominator (x^2+4x-21)(x+1) updates to (x-3)(x+7)(x+1)
We have three pairs of terms that will cancel between the numerator and denominator. The (x+1) terms pair up and cancel out, so do the (x+7) terms and also the (x-3) terms as well. Everything cancels out. The only thing left is 1 because x/x = 1 where x is nonzero. We can have a more complicated expression replace x to get the same basic idea. This is what I mean by "canceling".
Answer:
A.)
Step-by-step explanation:
HOPE IT HELPED:)!!
Knowing that one mile is 5,280 feet and an hour is 60 minutes:
10 x 5280 = 52800
60 x 1 = 60
52800 / 60 = <u><em>880 feet per minute</em></u>
Hope this helps!
