Answer:
D. 11655
Step-by-step explanation:
First find the 90th term:
a90=a1+(n−1)d
= -4+89(3)=263
Then find the sum:
Sn = n(a1 + an) / 2
S90 = 90 (-4 + 263) /2
S90 = 23,310/2
<u>S90 = 11,655</u>
Answer:
It will take 8 years.
Step-by-step explanation:
If the plant is already 14 inches and you want it to grow up to 38, then we subtract 14 from 38 and then divide the answer by 3 because in each year the plant will grow 3 inches, so then you get 8, which is the numbers of years.
38 - 14 = 24
24/3 = 8
I think it would have to equal a fraction being -4/3
