4(x - 2) - 3x = 2(5x - 7) + 6

after distributing and combining like terms, this problem should read:

7 - 8x = -10 + 8x

-15x = 10x - 8

8x - 6 = 7x - 3

-11x + 8 = 10x - 8

-7x + 8 = 10x - 8

Evaluate the dot product of (3,-1) and (1,5)

What is the next step in the given proof? choose the most logical approach. a. statement: m 1 + m 2 + 2(m 3) = 180° reason: angle addition b. statement: m 1 + m 3 = m 2 + m 3 reason: transitive property of equality c. statement: m 1 = m 2 reason: subtraction property of equality d. statement: m 1 + m 2 = m 2 + m 3 reason: substitution property of equality e. statement: 2(m 1) = m 2 + m 3 reason: substitution property of equality
