Answer:
Step-by-step explanation:
A = 176368374.8837477463636
3x + 21
(3)(x+7)
Now, we distribute the 3 in each term of (x+7)
So, 3*x = 3x and 3*7 = 21.
So our resulting term would be 3x+21.
You can refer to the given attachment
(-3)^13
(-3) is a constant value so there is no change
You must add 4 and 9 together to create one exponent of 13
