Question

Como simplifica essa expressão: 2*(x+5)+3*(5x+6):​

Answer 1

Answer:

17 x + 28

Step-by-step explanation:

Simplify the following:

2 (x + 5) + 3 (5 x + 6)

Hint: | Distribute 2 over x + 5.

2 (x + 5) = 2 x + 10:

10 + 2 x + 3 (5 x + 6)

Hint: | Distribute 3 over 5 x + 6.

3 (5 x + 6) = 15 x + 18:

10 + 2 x + 18 + 15 x

Hint: | Group like terms in 10 + 2 x + 18 + 15 x.

Grouping like terms, 10 + 2 x + 18 + 15 x = (2 x + 15 x) + (10 + 18):

(2 x + 15 x) + (10 + 18)

Hint: | Add like terms in 2 x + 15 x.

2 x + 15 x = 17 x:

17 x + (10 + 18)

Hint: | Evaluate 10 + 18 using long addition.
