Answer:
n=4
Step-by-step explanation:
First use distributive property to expand -10(n-2)
-5n-20=-20-10n+20
Simplify
-5n-20=-10n
Combine Like Terms
-20=-5n
Divide both sides by -5 to isolate "n"
n=4
Answer:
C) If the area of a square is an odd perfect square, the perimeter of the square will be even.
Step-by-step explanation:
Just did it on edge.
6r-24+r+30-7r (the we divide the regular numbers on one side and the others on the other side)Like this:
(6r+r-7r)+(-24+30)
(7r-7r)+6
And the final answer is 6
Answer:
Applying Quotient and power rule. Graphically, for x>0 both curves coincide.
Step-by-step explanation:
1) Firstly, by applying the Quotient and then the Power Rule, we have a subtraction of the argument and, finally the exponent turns to be the coefficient. As it follows:

2) Check the graph below to see this equivalence. to see x>0 they both coincide.
