Answer:
a = -5
Step-by-step explanation:
15 - a = 20
Move the constant of 15 to the other side by subtracting it.
-a = 5
Divide by -1 to make a positive.
a = -5
Check.
15 - (-5) = 20
15 + 5 = 20
20 = 20

Answer:
y=21 when x =15
Step-by-step explanation:
Since you multiply 5 by 3 to get 15, you also multiply 7 by 3. Therefore y=21
(n^3-8)(n^3+1)
It requires the same thought process of simplifying x^2-7x-8.
I would say it's "A is false, R is true"
Look at it this way, (R is talking): A is false, this is obviously true.
It wouldn't really work the other way.
