Question

4m-5m^2________2m-3При m=0,6​

Answer 1

Ответ:

Объяснение:

$\frac{4*0,6 - 5*0,6^{2} }{2*0,6-3} =\frac{2,4-5*0,36}{1,2-3} = \frac{2,4-1,8}{-1,8} =\frac{0,6}{-1,8}=-\frac{0,2}{0,6} =-\frac{0,1}{0,3}$

Answer 2

To evaluate the expression 4m - 5m^2 when m = 0.6, simply substitute the value of m into the expression and calculate the result:

4m - 5m^2 = 4(0.6) - 5(0.6)^2

Now, let's calculate it step by step:

4(0.6) = 2.4 0.6^2 = 0.36 5(0.36) = 1.8

Now subtract:

2.4 - 1.8 = 0.6

So, when m = 0.6, the value of the expression 4m - 5m^2 is 0.6.
