Answer:
Move all terms to the left side and set equal to zero. Then set each factor equal to zero.
x=5,−2
Step-by-step explanation:
I can do math
That is the combination of 10 over 3, which is calculated as the quotient of factorials:
n!/k!(n-k)!
where n = 10 and k = 3:
= 10!/3!(10 - 3)!
= 10!/3!*7!
= (10*9*8)/(3*2*1)
= 720/6
= 120
therefore there a re 120 possible different groups
If you would like to solve p = r - c for c, you can do this using the following steps:
p = r - c /+c
p + c = r - c + c
p + c = r /-p
p + c - p = r - p
c = r - p
The correct result would be c = r - p.
