Question

1) Efetue as operações com polinômios: M= 5t +8 N = 3t-20 P= -2t +8
a)M + N=
b)M + P=
c) M+N+P =​

Answer 1

Explicação passo-a-passo:

a) 5t+8+3t-20

8t-12

8t= 12

t= 12/8 (÷4)

t= 3/2

b) 5t+8-2t+8

3t+16

3t= -16

t= -16/3

c) 5t+8+3t-20-2t+8

6t-4

6t= 4

t= 4/6 (÷2)

t= 2/3

Answer 2

Resposta:

A)8t-12

B)3t+16

C)6t-4

Explicação passo-a-passo:

M=5t +8

N = 3t-20

P= -2t +8

a)M + N=

5t +8+3t-20

5t+3t-20+8

8t-12

b)M + P=

5t +8-2t +8

5t-2t+8+8

3t+16

c) M+N+P =

5t + 8 + 3t -20 -2t +8

5t+3t-2t+8-20+8

6t-4
