a) y + y + y _____________
b) 4x + x ______________
c) 25 x²yz - 8 x?yz + 2 xyz _______________​

Answer 1

Explicação passo-a-passo:

a)

$\sf{y + y + y } \\ \sf{2y + y} \\ \boxed{\red{\mathsf{3y}}}$

b)

$\sf{4x + x} \\ \boxed{\red{\mathsf{5x}}}$

c)

$\sf{25 {x}^{2} yz - 8x} \\ \boxed{\red{\mathsf{x \times (25xyz - 8)}}}$

d)

$\sf{yz + 2xyz} \\ \boxed{\red{\mathsf{yz \times (1 + 2x)}}}$
