The answer to the expression is 2y-12
You can divide the whole expression by -3:

Recalling that

Let's compare the middle term:

So, we want to complete

Which differs from
by 16. So, if we add 16 to both sides, we have

6.5 - 3 = 3.5
11 - 6.5 = 4.5
16.5 - 11 = 5.5
23 - 16.5 = 6.5
From this, you can see that the number being added is increasing by 1 each time.
Therefore, the pattern is adding 3.5, then 4.5, then 5.5, then 6.5, and so on.
Hi there!
Let's solve this problem step by step!

To find f(3) we must substitute x = 3 into the formula.

Now we use PEMDAS (Parenthesis, exponents, multiply, divide, add, subtract) to find our answer.
Work out the exponents inside the parenthesis first.

And finally multiply.

Hence, the answer is D. 64.

Midpoints are points in the middle, so I believe they are Midpoints: D, F and E
