This is a whole squared equation. So, it is (x+2)^2.
If you check it, you get x2 + 4x + 4
Hope this helps!

You end with 210.85. add 75.50 and 55.25 together you get 130.75. 130.75-25.15-18.65 = 86.95. 210.85-86.95= 123.90 work backwards.
Answer:
d = 17
Step-by-step explanation:
The given arithmetic sequence is :
31, 48, 65, 82, ...
We need to find the common difference for this sequence.
First term, a₁ = 31
Second term, a₂ = 48
Common difference = a₂-a₁
= 48-31
= 17
So, the common difference for this arithmetic sequence is equal to 17.
Answer:
27
Step-by-step explanation:
If k/3 = 9
K must be 27
because 9*3=27
and to check we can do
27/3
and 27/3 = 7
