Answer: Option A. 288 cubic inches
Answer:

Step-by-step explanation:
Let x be the number
- Write it out: -26x - 22 = x - 90
- Combine like terms: -27x + 68 = 0
- Subtract 68 from each side, so it now looks like this: -27x = -68
- Divide each side by -27 to cancel out the -27 next to x. It should now look like this:
I hope this helps!
18 - h = 13 when h = -5
18 - (-5) = 13
18 + 5 = 13
23 = 13
False, h would need to equal +5
Hope this helps! ;)
