What is the value of cd if c=7 and d=6

42 because 7•6 is 42

Answer: + 42

Step-by-step explanation: In this problem we are going to evaluate cd knowing that c = 7 and d = 6.

So the first thing we want to do is substitute

these numbers into our problem.

Since c = 7, we are going to replace this c with a 7 and as we do that, we are going to put that 7 in parentheses.

Make sure to get into the habit of putting numbers in parentheses when substituting them in for variables.

Now we will replace the d with the 6.

So we now have (7) (6) which simplifies to + 42.
