S= a/4 + 8u
S - 8u = a/4 (First you subtract 8u from both sides)
4(S - 8u) = a ( Then you multiply both sides by 4)
Final answer:
4(S - 8u) = a
Yes because 4x3^x =12^x since the coefficient is added to the answer because it is in the 3.
It would be 1/8. 2 to the third is 8, and all three answers correct is one option.
71 * 4 = 284
The answer is 284
The answer to c is 0 and the answer to d is undefined
