<h3>
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:

Step-by-step explanation:
Answer:
8(1/x) = 4(1/10)
Step-by-step explanation:
lets say the number is x
eight times the reciprocal of a number equals 4 times the reciprocal of 10
8 * 1//x = 4 * 1/10
8/x = 4/10 , cross multiply
4x =8*10, divide both sides by 4
x= 80/4
x= 20
The last one that looks like a V
Answer:
The mode is the number that shows up most frequently
Step-by-step explanation:
