im not really sure about this since i think you can just stop at equation 1
We will call the first number n, and the second number x.
3n-x=118
2n+x=147
Now, solve one of the equations for x.
x=147-2n
Then, substitute this into the other formula for x.
3n-(147-2n)=118
Next, solve for n:
3n-147+2n=118
5n=265
n=53
^^^That's your first number.
Lastly, plug in 53 for n into either equation to solve for x.
2(53)+x=147
106+x=147
x=41
^^^This is your second number.

Answer:
I only can see that one of them are B i don't know for the rest
Step-by-step explanation:
Write 4 as a sum (8h-3j)^2+2
Use a m+n=a m•a n to expand the expression
(8h-3j)^2 x (8h-3j)^2
Use (a-b)^2= a^2... -2ab+b^2 to expand the expression
(64h^2 - 48hj+ 9j^2)x(64h^2 - 48hj+ 9j^2)
Multiply the parentheses and after you get your answer you collect like terms.
Your answer should be:
4096h^4 - 6144h^3j + 3456h^2j^2 - 864hj^3 +81j^4
