Answer 1

Ответ:

(5m-4)-4(3m+2) если m=-0,2

(5m-4)-4(3m+2)=5m-4-12m-8=-12-7m

-12-7×(-0,2)=-12+1,4=-10,6

Answer 3

Sure, let's solve the expression step by step. Given the expression:

(5m - 4) - 4(3m + 2)

And the value of m is given as m = -0.2. We'll substitute this value into the expression and simplify it.

Step 1: Substitute the value of m into the expression.

(5(-0.2) - 4) - 4(3(-0.2) + 2)

Step 2: Simplify inside the parentheses.

(-1 - 4) - 4(-0.6 + 2)

Step 3: Continue simplifying.

-5 - 4(-0.6 + 2)

Step 4: Simplify the expression inside the second set of parentheses.

-5 - 4(1.4)

Step 5: Perform the multiplication.

-5 - 5.6

Step 6: Perform the subtraction.

-10.6

The result of the expression (5m - 4) - 4(3m + 2) when m = -0.2 is -10.6.
