Answer:
Step-by-step explanation:
<u>Solving in steps</u>
- 7^-1/7^2 =
- 7^-1 × 7^-2 =
- 7^(-1 - 2) =
- 7^-3
(X+5)+(2y+4x-2)
X+5+2y+4x-2
5x+2y+3
Hope this helps!
6x + (-9) or 6x - 9
Try looking at the terms for the same things. Such as the variable like X and the negatives add together and make a negative
1/5 because you divide them both equally by 2 and then by 2 and then by 3 and you get 1 and 5. :)
