Question

4(1.5-2)-(-4*-0.4+1.5)+(3*-0.4+7*2)*2

Answer 1

Ответ:

Пошаговое объяснение:

4(1.5-2)-(-4*-0.4+1.5)+(3*-0.4+7*2)*2 = 4*(-0,5) -(1,6 + 1,5) + (-1,2 + 14)*2 = -2 - 3,1 + 25,6 = 20,5

Answer 2

To evaluate the given expression, let's break it down step by step:

Step 1: Calculate the expressions inside parentheses: 4(1.5 - 2) = 4(-0.5) = -2

-(-4 * -0.4 + 1.5) = -(-1.6 + 1.5) = -(-0.1) = 0.1

(3 * -0.4 + 7 * 2) = (-1.2 + 14) = 12.8

Step 2: Substitute the results back into the main expression and perform the remaining calculations:

-2 + 0.1 + (12.8 * 2)

Step 3: Continue evaluating the expression:

-2 + 0.1 + 25.6 = -1.9 + 25.6 = 23.7

Therefore, the value of the expression 4(1.5-2)-(-4*-0.4+1.5)+(3*-0.4+7*2)*2 is 23.7.
