Answer:
C
Step-by-step explanation:
When doing vertical subtraction, 800 - 675 will turn out like this:
800
- <u>675
</u><u>
</u>You should know that we start on the right and then end on the left.
<u>
</u>So, we do 0 - 5, 0 - 7, then 8 - 6, right?
No. We have to borrow because you can't have a negative number when doing each number individually, only until the end. In this case, there won't be any negative numbers.
<u>
</u>You can't do 0 - 5 or 0 - 7, so you have to borrow, changing the number to the left of it one lower (unless it's 0, so then you must borrow the the next number after that).<u>
</u>
(5x+4)(x+7) = (5x × x) + (5x × 7) + (4 × x) + (4 × 7)=
= 5x^2 +35x + 4x + 28 = 5x^2+39x+28
