Question

3(2x +1) + 5 (1 + 3x)​

Answer 1

Ответ:

$3(2x +1) + 5 (1 + 3x) = 6x+2+5+15x=21x+7$

Answer 2

To simplify the expression 3(2x + 1) + 5(1 + 3x), we can distribute the numbers outside the parentheses to the terms inside.

First, distribute 3 to (2x + 1): 3(2x + 1) = 3 * 2x + 3 * 1 = 6x + 3

Next, distribute 5 to (1 + 3x): 5(1 + 3x) = 5 * 1 + 5 * 3x = 5 + 15x

Now we can combine like terms by adding the simplified expressions: 6x + 3 + 5 + 15x

Combining the like terms, we get: (6x + 15x) + (3 + 5) = 21x + 8

Therefore, the simplified expression is 21x + 8.
