Question

Evaluate the expression for c = –9 and d = –5.

cd + c + d

Answer 1

31

Explanation:

Because c = -9 and d = -5, we replace the variables in the expression with the corresponding numbers.

cd + c + d --- > (-9)(-5) + (-9) + (-5)

Then we solve it.

(-9)(-5) + (-9) + (-5)

45 + (-9) + (-5)

36 + (-5)
