Question

0.8(3a-14)-0.6(6a-8)​

Answer 1

Решение:

0.8(3a-14)-0.6(6a-8)=2,4a-11,2-3,6a+4,8=2,4a-3,6a-11,2+4,8=-1,2a-6,4

Ответ: -1,2a-6,4

Answer 2

To simplify the given expression, follow these steps:

1. Distribute the coefficients through the parentheses.
2. Combine like terms.

Let's start:

0.8(3a - 14) - 0.6(6a - 8)

Step 1: Distribute the coefficients through the parentheses.

0.8 * 3a = 2.4a 0.8 * (-14) = -11.2

-0.6 * 6a = -3.6a -0.6 * (-8) = 4.8

Now, the expression becomes:

2.4a - 11.2 - 3.6a + 4.8

Step 2: Combine like terms.

(2.4a - 3.6a) = -1.2a

Now, the simplified expression is:

-1.2a - 11.2 + 4.8

Finally, combine the constant terms:

-1.2a - 6.4

So, the simplified expression is -1.2a - 6.4.
