Question

Preciso Urgentemente

Answer 1

Resposta:

Olá!

Explicação passo-a-passo:

6. a) $9m+7+10m$

$19m+7$

b) $4.(x-1)+2.(x+1)$

$4x-4+2x+2$

$6x-2$

$2.(3x-1)$

c)$-2.(2x-4)-5.(-2x+10)$

$-4x+8+10x-50$

$6x-42$

$6.(x-7)$

d)$-\frac{3}{2} x+\frac{1}{3}a+\frac{1}{3}x-\frac{1}{2}a$

$-\frac{3}{2} x+\frac{1}{3}x+\frac{1}{3}a-\frac{1}{2}a$

$\frac{-9+2}{6} x+\frac{2-3}{6}a$

$-\frac{7}{6}x-\frac{1}{6} a$

$-\frac{1}{6}.(7x+1 a)$

e) $\frac{2p}{3}-\frac{y}{2}-\frac{5p}{8} +y$

$\frac{2p}{3}-\frac{5p}{8}-\frac{y}{2} +y$

$\frac{16p-15p}{24}-\frac{y+2y}{2}$

$\frac{p}{24}+\frac{y}{2}$

$\frac{p+12y}{24}$

$\frac{1}{24} .(p+12y)$

Bons Estudos!
