4. Simplifique as expressões, reduza os termos semelhantes:
a) 4b + 3c – a + 4a – 3b – 2c =
b) 10x + 20y – 5x + 15y =
c) 5x + y2+ 4 – x + 7y² =
d) 8x5+ 4x2+ 22 – 17 x5 =

Answer 1

Resposta:

OLÁ

VAMOS A SUA PERGUNTA:⇒⇒

A:)→

$4b+3c-a+4a-3b-2c$

$4b+3c+3a-3b-2c$

$b+3c+3a-2c$

$\star \ \text{Combine 3c e -2c para obter c.}$

$\boxed{\bold{\displaystyle{\clubsuit\ \spadesuit\ \maltese\ \red{b+c+3a} }}}\ \checkmark$

B:)→

$10x+20y-5x+15y$

$5x+20y+15y$

$\star \ \text{Combine 20y e 15y para obter 35y.}$

$\boxed{\bold{\displaystyle{\clubsuit\ \spadesuit\ \maltese\ \red{5x+35y}}}}\ \checkmark$

C:)→

$5x+y^2+4-x+7y^2$

$4x+y^2+4+7y^2$

$\star \ \text{Combine }$ $y^2$ e $7y^2$ $\text{para obter}$ $8y^2$

$\boxed{\bold{\displaystyle{\clubsuit\ \spadesuit\ \maltese\ \red{4x+8y^2+4 }}}}\ \checkmark$

D:)→

$8x5+4x2+22-17x5$

$\star \ \text{Combine}$ $8x_{5}$ e $-17x_{5}$ $\text{para obter -9x}$$_{5}$

$\boxed{\bold{\displaystyle{\clubsuit\ \spadesuit\ \maltese\ \red{-9x_{5}+4x_{2}+22}}}}\ \checkmark$
