Steps to solve:
(-5q^2 + 6q + 7) - (-q^2 + 4q)
~Distribute the left side
-5q^2 + 6q + 7 + q^2 - 4q
~Combine like terms
-4q^2 + 2q + 7
Best of Luck!
Answer:
I just looked it up and that is correct!
The number 35.4 when rounded to the nearest tenth is 5.4
Answer: $389.35
Step-by-step explanation: Multiply $599 by .65, to get the 35% off price.
There is also another way you can do this kind of problem. You multiply $599 by .35, then subtract that number from 599. I prefer the first method because it is faster.

Answer:
terms were improperly combined
Step-by-step explanation:
I find the easiest way to identify the error in a solution is to solve it myself and compare with what is shown as being done.
Here, we're starting with ...

If we identify the g-terms and the constant terms, we can group them the way Tyson did:

The next step is to combine like terms. We can factor out g, so the coefficients are easier to see and combine.

The error is 1 3/10 was combined with -2/10 as a constant instead of being combined with -4/5 as a coefficient of g.
