Evaluate 3(a+b) for a=− 1/2 and b=2 1/2 . Record the answer in the simplest way.

3(1/2 + 2 1/2) = 3(1/2+5/2) = 3(6/2) = 3*3 = 9

Step-by-step explanation:

Step-by-step explanation:

Since we know that a equals -1/2 and b equals 2 1/2, then we can plug in the values into the equation.

First, solve everything in the parentheses.

Now, multiply 3 by 2.

So, your answer will be 6.

there are three prime numbers with only 1 and themselves as factors so i say one is the greatest common factor for all of them.
