x² - 36 = (x + 6) (x - 6)

Multiply those out and you'll see.

Find GCF of x^6 and x^5

Answers

x^6 = x * x * x * x * x * x

x^5 = x * x * x * x * x

The GCF is the greatest number of xs that each has in common. They are in bold. There are 5 xs that each of the terms have.

GCF = x^5

x^6 = x^5 * x

So GCF of x^6 and x^5 = x^5

How do you get 34 from P = 5s - (100 + 2s) when P = 0 is s ≈ 33.333.

Answers

P = 5s - (100 + 2s)           Carefully remove the brackets. Watch the signs.
P = 5s - 100 - 2s
P = 3s - 100

0 = 3s - 100 Add 100 to both sides.
100 = 3s Divide by 3
100/3 = s

s = 33.33333  It is just a rounding factor. It depends on what you are really finding. So whatever answers you're given (if any), choose the one closest to 33.33333 which is likely what you got when you did it.
P = 5s - (100 + 2s)
when P = 0

0 = 5s - (100 + 2s)
0 = 5s - 100 - 2s
0 = 3s - 100
100 = 3s
s = 100/3
s = 33.3333....

The mean of a set of data is 45 years. Find the missing numbers in the data set {40, 45, 48, ?, 54, ?, 45}. Explain the method or strategy you used.

Answers

There are 7 numbers.  7 X 45 equals 315.  40+45+48+54+45=232.
315-232=83.

The 2 numbers can each have different values, such as 41 and 42, or 40 and 43.  The numbers must add up to 83, though.
