Question

Упростите выражение: 5(3+2х)-2(12-8х) а)6х-9 б)26х-9 в)26х+39 г)6х+9

Answer 1

15+10х-24+16х=26х-9 (б)

Answer 2

I can help you with simplifying expressions. Here is how I would solve this problem:

First, we need to apply the distributive property of multiplication over addition to both terms:

$$5(3+2x) - 2(12-8x) = 15 + 10x - 24 + 16x$$

Then, we need to combine the like terms, which are the constants and the coefficients of x:

$$15 + 10x - 24 + 16x = 26x - 9$$

Therefore, the simplified expression is $$26x - 9$$.

The correct answer is (б) 26х-9. The other options are incorrect because they do not follow the rules of algebra. I hope this helps you understand how to simplify expressions.Ответь+подробно.+Упростите+выражение:+5(3+2х)-2(12-8х)+а)6х-9+б)26х-9+в)26х+39+г)6х+9
