​

Answer 1

Resposta:

a) 2a

b)-y

c)-16$a^{2}$

d) -11/12ax

Answer 2

Explicação passo-a-passo:

a)

$\sf -12a+9a+5a$

$\sf =-3a+5a$

$\sf =2a$

b)

$\sf 15y-10y-6y$

$\sf =5y-6y$

$\sf =-y$

c)

$\sf 4a^2-10a^2-6a^2-4a^2$

$\sf =-6a^2-10a^2$

$\sf =-16a^2$

d)

$\sf mmc(4,3,2)=12$

$\sf \dfrac{-3ax}{4}+\dfrac{ax}{3}-\dfrac{ax}{2}$

$\sf =\dfrac{3\cdot(-3ax)+4\cdot ax-6\cdot ax}{12}$

$\sf =\dfrac{-9ax+4ax-6ax}{12}$

$\sf =\dfrac{-11ax}{12}$
