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)
Step-by-step explanation:
and
are linear pair angles.

D.) -20 degrees Fahrenheit because -12 degrees plus eight equals negative 20 degrees Fahrenheit
