2)(-15)*c*(-d),если c= 0,2,d=3,5 3) -5*у*х,если х=5,2,y=0,7 4)0,25 * (-m) * (-N),если m = -2,4, n=6,4

Answer 1

Пошаговое объяснение:

2. (-15)*0,2*(-3,5)=3*3,5=10,5

3. -5*0,7*5,2=-26*0,7=-18,2

4. 0,25*(-(-2,4))*(-6,4)=0,25*2,4*(-6,4)=-3,84

Answer 3

To solve each of these expressions, simply substitute the given values for the variables and perform the calculations:

1. (-15) * c * (-d), if c = 0.2, d = 3.5

(-15) * 0.2 * (-3.5)

Now, multiply the numbers:

(-15) * 0.2 = -3

-3 * (-3.5) = 10.5

So, the result is 10.5.

2. -5 * y * x, if x = 5.2, y = 0.7

-5 * 0.7 * 5.2

Now, multiply the numbers:

-5 * 0.7 = -3.5

-3.5 * 5.2 = -18.2

So, the result is -18.2.

3. 0.25 * (-m) * (-N), if m = -2.4, n = 6.4

0.25 * (-(-2.4)) * (-6.4)

First, simplify the double negation:

0.25 * 2.4 * (-6.4)

Now, multiply the numbers:

0.25 * 2.4 = 0.6

0.6 * (-6.4) = -3.84

So, the result is -3.84.
