Answer:
$156 for 4 g
I did not rally understand how you worded your question so sorry if I got it wrong! <3
Step-by-step explanation:
$156 for 4 g =
$156 / 4 = $39 dollars for 1 g
$280 for 7 g =
$280/7 = $40 dollars for 1 g
-2x + 6 = -2x + 6
this problem has infinite solutions :)
For both of these questions you want to raise every part to the 4th or 2nd power. Just remeber that a power raised to a power is just multiplied.
3.)
3^4 = 3×3×3×3 = 9×9 = 81
x^4 = 1×4 = 4 so x^4
2^4 = 2×2×2×2 = 4×4 = 16
so

4.)
2^2 = 2×2 = 4
5^2 = 5×5 = 25
(n^9)^2 = 2×9 = 18 so n^18
so

Hope this helps!
I am 100% sure it is A. I did the test and it showed it was A.
