Evaluate the expression for a = –1 and b = 5.
5a – 7b + b^2
= 5*(-1) - 7*5 + 5^2
= -5 - 35 + 25
= -40+ 25
= -15 .

Solve the equation. SHOW YOUR WORK. 3x - 7 = 5x + 19 and then check your answer
Weegy: 3x - 7 = 5x + 19 3x - 5x = 19 + 7; -2x = 26; x = 26/-2; x = -13; Check: 3(-13) - 7 = 5(-13) + 19; -39 - 7 = -65 + 19; -46 = -46 (More)
