Question

(a+b)•c=ac+bc a=0,5b=0,3c= -0,4​

Answer 1

-0,32=-0,20-0,12
0,32=0,32

Answer 2

Let's substitute the values of a, b, and c into the equation and see if it holds true:

(a + b) • c = ac + bc

a = 0.5 b = 0.3 c = -0.4

Now, plug these values into the equation:

(0.5 + 0.3) • (-0.4) = (0.5 * -0.4) + (0.3 * -0.4)

(0.8) • (-0.4) = (-0.2) + (-0.12)

-0.32 = -0.32

So, the equation (a + b) • c = ac + bc holds true with the given values of a, b, and c.
