(x^2) - 16 / x+4 = (x-4)(x+4) / (x+4) = x-4, x not equal to -4
D is the answer.
Answer:

Step-by-step explanation:
Given
Square

Triangle


Required
Find h, if both shapes have the same area
The area of the square is:


The area of the triangle is:


Equate both areas

Divide both sides by x

Multiply both sides by 2



Answer:
Increase?
Step-by-step explanation:
Because think about it let's use 1/2 as an example.
1/2 equals .5 now lets add 2 to both the numerator and denominator
3/4 is the result and it also equals .75 which is larger than .5 so that's why the answer is increase.
and u can keep on going on with the method
4/5=.8
Answer:
You can either factor or use quadratic formula to find where h(x)=0
Step-by-step explanation:
Remember that the ball is on the ground when h(x)=0 since that is the height. There will be two zeros, one is a negative number so would be before you kicked the ball, the other one will be when the ball comes back down.
The terms in the sum are given by the sequence

We have

for all
, and the series
clearly diverges, so
must also diverge.
