Question

mim ajudem por favor! !!

Answer 1

a) 2x + 2 (x-3) = 2x + 2x - 6 = 4x - 6
b) 2 (x + 5) + 2 . 2(x - 3) = 2x + 10 + 4x - 12 = 6x - 2
c) 5 (x - 3) = 5x - 15
d) (x + 5) x (2x - 6) = 2x² - 6x + 10x - 30 = 2x² + 4x - 30
e) (6x - 2) - (4x - 6) = 6x - 2 - 4x + 6 = 2x + 4
f) (2x² + 4x - 30) - (5x - 15) = 2x² + 4x - 30 - 5x + 15 = 2x² - x - 15
