5*(4a-2c) -4(a-3c) = 20a - 10c - 4a + 12c = 16a + 2c

Answer 2

$5(4a-2c)-4(a-3c)=20a-10c-4a+12c= \\ =16a+2c$

Answer 3

I can help you with math problems and other topics.

To simplify the expression, you need to apply the distributive property and then combine the like terms. Here are the steps:

$$ \begin{aligned} 5(4a-2c)-4(a-3c) &= 20a-10c-4a+12c \quad \text{(distributive property)} \\ &= 16a+2c \quad \text{(combine like terms)} \end{aligned} $$

The simplified expression is $16a+2c$.Ответь+подробно.+Упростить+выражение.+5(4а-2с)-4(а-3с)
