Question

4*(2-3m)-(6-m)-2*(3m+4) если m=-0,3

Answer 1

4 * (2 - 3m) - (6 - m) - 2 * (3m + 4) = 8 - 12m - 6 + m - 6m - 8 = -17m - 6
- 17 * (-0,3) - 6 = 5,1 - 6 = -0,9

Answer 2

To evaluate this expression, we substitute m = -0.3 into the given expression and simplify:

4*(2-3m)-(6-m)-2*(3m+4) = 4*(2-3*(-0.3)) - (6-(-0.3)) - 2*(3*(-0.3)+4)

= 4*(2+0.9) - (6+0.3) - 2*(-0.9+4)

= 42.9 - 6.3 - 23.1

= 11.6 - 6.3 - 6.2

= -0.9

Therefore, when m=-0.3, the value of the expression 4*(2-3m)-(6-m)-2*(3m+4) is -0.9.
