Question

А)(-5,8+3,6)*(-1,2)-4,04 б)-6.03*2,1-(0,14)*(-0;05)

Answer 1

A)-1,60
b)12.67 вот это ответ

Answer 2

To evaluate the given expressions, let's simplify each step:

A) (-5.8 + 3.6) * (-1.2) - 4.04

First, let's simplify the parentheses: (-5.8 + 3.6) = -2.2

Now substitute the simplified values back into the expression: -2.2 * (-1.2) - 4.04

Multiply -2.2 and -1.2: 2.64 - 4.04

Finally, subtract 4.04 from 2.64: -1.4

Therefore, the value of expression A is -1.4.

B) -6.03 * 2.1 - (0.14) * (-0.05)

Multiply -6.03 and 2.1: -12.663

Now let's simplify the second part: (0.14) * (-0.05) = -0.007

Now substitute the simplified values back into the expression: -12.663 - (-0.007)

When subtracting a negative number, it becomes addition: -12.663 + 0.007

Finally, subtract 0.007 from -12.663: -12.656

Therefore, the value of expression B is -12.656.

To summarize: A) (-5.8 + 3.6) * (-1.2) - 4.04 = -1.4 B) -6.03 * 2.1 - (0.14) * (-0.05) = -12.656
