The expression that is equivalent to the given expression is:

<h2>
Step-by-step explanation:</h2>
Two expression are said to be equivalent if by some simplification i.e. by some multiplication or division it could be represented in the same manner.
Here we are given a expression as:
g^{-m} ÷ g^n i.e.

We know that:

Hence, we get:

Answer: 1/2+11/3 = 4.1*6
Step-by-step explanation:
S=2d
4s+3d=300000-80000
4s+3d=220000, now using s=2d in this equation you get:
4(2d)+3d=220000
8d+3d=220000
11d=220000
d=20000
So each daughter gets 20000 and each son gets 40000.
Answer:
10x²+11-2x
Step-by-step explanation:
I hope you mean 7x²+8+5, not 7x²+8x+5.
We need to combine like terms. Anything with squared should be added together, et cetera.
(7x²+8+5)+(3x²-2x-2)
You can take out the parenthesis, because they don't matter in addition.
7x²+8+5+3x²-2x-2
Add the terms, step by step. Each bold pair needs to be added together.
7x²+8+5+3x²-2x-2
10x²+8+5-2x-2
10x²+11-2x
Now there's no more we can add together.
