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.
5/g=n because the denominator is always the total amount and g is the total amount of granola bars in the box. And the 5 comes from the amount of kids that received the bars and the n is on the outside because your looking for that amount. I’m sorry if this doesn’t make sense, i tried my best to explain.
