Is 192 rational , why is it?
Oduvanchick [21]

Answer: 192 IS IRRATIONAL. I HOPE THIS ANSWER HELPS.

Step-by-step explanation:

It is an irrational number if it is not a perfect square. Since 192 is not a perfect square, it is an irrational number. This means that the answer to "the square root of 192?" will have an infinite number of decimals. The decimals will not terminate and you cannot make it into an exact fraction.

What is the value of x in the following equation? -3x-2=2x+8
Arlecino [84]

Answer:

-2 =x

Step-by-step explanation:

-3x-2=2x+8

Add 3x to each side

-3x+3x-2=2x+3x+8

-2 = 5x+8

Subtract 8 from each side

-2-8 = 5x+8-8

-10 = 5x

Divide by 5

-10/5 = 5x/5

-2 =x
