Question

(a+b)•c = ac+bc, a=0,2, b=-0,3,c=-0,

Answer 1

На ноль же умножается ... ответ ноль..

Answer 2

Let's evaluate the expression (a+b)•c and see if it equals ac + bc when a = 0.2, b = -0.3, and c = -0.

(a + b) • c = (0.2 + (-0.3)) • (-0)

To calculate this, first, we add a and b: 0.2 + (-0.3) = -0.1

Next, we multiply the result by c: -0.1 • (-0) = 0

Now, let's calculate ac + bc:

ac + bc = (0.2 • (-0)) + (-0.3 • (-0))

Any number multiplied by 0 is always 0, so both terms become 0:

0 + 0 = 0

Comparing the two results:

(a + b) • c = 0 ac + bc = 0

We can see that both expressions are equal to 0, which means the statement (a + b) • c = ac + bc is true when a = 0.2, b = -0.3, and c = -0.
