First, take half of the coefficient of 18x then square it.
18 / 2 = 9
9^2 = 81
So, D. 81 is the answer.
Answer:
t = 350
Step-by-step explanation:
subtract 250 from each side, and then you'll have t = 350
The solution to the equation would be 21.5
Why?
If you do the equation backwards
30 - 8.5 = x
You would get 21.5
You can plug it into the first equation to check!

3 and 60 are the extremes while 15 and 12 are the means.
