Answer:
I think. its below
Step-by-step explanation:
1 x 8 = 8
4 x 8 = 32
Answer:
See explanation
Step-by-step explanation:
The standard compound interest formula is 
where:
P is the principal amount
r is the interest rate (typically as a percentage)
t is the time
n is the times compounded per unit of time
So,
1) 
2) 
3) 
You should check my answers though, I may have mixed up some terms.
4x+2x^2+3x-2x+7
First, you would combine like terms. In this case, you would add 4x and 3x then subtract 2x.
2x^2+5x+7
5x^2-2x+3+4x-2x^2
Once again, you must combine like terms. Subtract 2x^2 from 5x^2, then subtract 2x from 4x.
3x^2+2x+3
There you go! Hope it helps

Another way: A perhaps more natural way to attack the problem is to imagine choosing the shoes one at a time. The probability that the second shoe chosen does not match the first is 2−22−1

This can be expressed more compactly in various ways.
Answer:
48 + 48 solve it and that is your answer
