Answer:

Correct choice: 72

Step-by-step explanation:

Multiplication

In math, to multiply means to add equal groups. For example, 5 groups of 7 people add up to 5*7=35 people.

When multiplying variables (letters), it's common to omit the cross (x) or dot (.) signs to indicate multiplication.

The expression cd, when c and d are separate variables, should be interpreted as c by d.

We are given c=9 and d=8, thus

cd = 9*8 = 72

Correct choice: 72
