Answer:
1) It would be about a 55% increase. 2) It would be about a 79% increase
Step-by-step explanation:
I used process of elimination to figure out how much of a percentage would be needed by just multiplying 210 by different percentages until I found the answer.
Sorry I don't have like a definite formula or anything for you to figure these questions out... I hope someone else answers with a more definite answer!
I believe if that says three minus four times three minus five or three plus negative four times three plus negative five (same thing) then the answers should be positive two (2.)
3x^2 + 4x - 21x - 28
x(3x + 4) - 7(3x + 4)
(3x + 4) (x - 7)
Answer: B).
