Hi Grant.
(3x + 5) + (2x - 9) is what we'll start with. Considering we cannot combine variables with numbers, we can only combine like-terms.
3x + 2x; 5 - 9; we result with: 5x - 4
Now, we are left with (5x - 4) - (4x + 3)
Remember to distribute the negative sign to everything to the right.
(5x - 4) - 4x - 3. We are now able to simplify and solve for our answer.
5x - 4x; -4 - 3; we result with x - 7.
Your answer is A.) x - 7.
I hope this helps!

Answer:
3840 cubic inches
Step-by-step explanation:
The volume of a rectangular prism is 960 cubic inches
Let the dimensions be lXwXh,
l=length of the base
w=width of the base
h=height of the base
The volume, lwh=960 cubic inches
If the dimensions of the base are doubled and the height remains the same
Volume of the new rectangular prism=2l X 2w X h =4lwh
=4 X 960 =3840 cubic inches
