Answer:
(2v +7)(v -9)
Step-by-step explanation:
Factors of 2·(-63) = -126 that have a sum of -11 are 7 and -18, so we can rewrite the middle term to -18v+7v. Then we can factor by grouping.
2v^2 -18v +7v -63 = 2v(v -9) +7(v -9)
= (2v +7)(v -9)
Answer:
r=7
Step-by-step explanation:
5r-7=2r+14
add sevento both sides
5r=2r+21
Subtract 2r from both sides.
3r=21
divide both sides by 3
r=7
