If you distribute -5 to the things in the parenthesis you would get 10k-20 which is the same as -5(-2k+4)
Answer:
D.
Step-by-step explanation:
m<F = m<B - Corresponding Angles Theorem
m<B + m<A = 180 - Adjacent Angles Theorem
180 - 105 = m<A
75 = m<A; therefore, m<A = 75.
Divide 1440 by 6 to get 240 packs.
