Original conversation
User: Simplify: 5(3x + 7)

Weegy: Distribute 5(3x)+5(7) = 15x + 35 can also be written in this form : 15x + 35 = 15(x+3)

User: Evaluate: x2 – 5x + 3 for x = -5

Weegy: Substitute x to the value of -5 : x^2 - 5x + 3 = (5)^2- (5(-5)) + 3 = 25 + 25 + 3 = 53 : Meaning x^2 - 5x + 3 = 53 if x = -5.
