Пошаговое объяснение:

$8(4,5a-0.3)-3.5(4-12a)=36a-2.4-14+42a=78a-16.4$

Answer 2

To solve the expression 8*(4.5a - 0.3) - 3.5*(4 - 12a), we can apply the distributive property and simplify the expression step by step. Let's break it down:

Step 1: Distribute the 8 and the 3.5 to the terms inside the parentheses. 8 * 4.5a - 8 * 0.3 - 3.5 * 4 + 3.5 * 12a

Step 2: Multiply the numbers. 36a - 2.4 - 14 + 42a

Step 3: Combine like terms. (36a + 42a) - 2.4 - 14

Step 4: Add the coefficients of 'a.' (36 + 42)a - 2.4 - 14

Step 5: Simplify. 78a - 2.4 - 14

Step 6: Combine the constant terms. 78a - 16.4

So, the simplified expression is 78a - 16.4.
