Answer:
B.) 24(y² -1)
Step-by-step explanation:
The denominator of the first fraction is 2³(y +1).
The denominator of the second fraction is 2·3(y +1)(y -1).
The LCD is the product of the unique factors to their highest powers:
2³·3·(y +1)(y -1) = 24(y² -1)
The "20" under <em>n</em> means "When <em>n</em> is 20,". Therefor, on the other side of the table, 5n-2 would be 5(20)-2. 5*20=100, 100-2 is 98. The top missing value is 98.
For the other side, it's saying that 5n-2 is 38. You have to work backwards to get your answer. The opposite of -2 is 2, so 38 + 2 is 40. The opposite of *5 is /5, so 40/5 is 8. The bottom missing value is 8.
26 miles per gallon is your answer you divide 208 miles by 8 finding out how many miles per gallon you drive. To check your answer you can multiply 26 times 8 and you get 208 miles.
The correct answer would be D
