B and C cant be it because its not a whole number and it is .4 so it cant go up one making D the only possible choice.
I'm assuming the integral is

We have

Then substituting
and
, the integral transforms and reduces to

which we can rewrite as

and so

Answer:
4(3x +8)
Step-by-step explanation:
You are being asked to factor 4 from each of the terms of the expression and use the distributive property to show the result.
12x +32
= 4(3x) +4(8)
= 4(3x +8)
The numbers that go in the boxes, left to right, are ...
4, 3, 8
You solve this by plugging one equation into the other. Usually you have to rewrite one equation to make this work. In this case I choose to rewrite y-4x=0 as y=4x.
After plugging it into the second, you get:
3x + 6*4x = 9 => 27x = 9 => x=1/3
Putting this solution back into y=4x gives us y=4/3
