Question

hola me podrian ayudar a resolver por fabor es urgente gracias

Answer 1

(1) 3(a+b) = 3a +3b
(2) 5(2x +3y) = 10x +15y
(3)
$\frac{1}{2} (6m + 8n) \\ = \frac{6m}{2} + \frac{8n}{2} \\ = 3m + 4n$
(4) -2(3x²+5x) = -6x² -10x
(5)
$- \frac{1}{3} ( - 9a + 27b) \\ = \frac{9a}{3} - \frac{27b}{3} \\ = 3a - 9b$
(6) -5(6x⁴-3x²) = -30x⁴ +15x²
(7) -2(4x²+x-1)= -8x² -2x +2
(8)5(a+2b+3c) = 5a +10b +15c
(9)-2(5a²-b²+3) = -10a² +2b² -6
(10)-4(2x²-6x+1) = -8x² +24x -4
