Question

To evaluate the expression cd - d + 2e + 10 when c = 5, d = 3, and e = 9, we need to substitute these values into the expression.

Therefore,

cd - d + 2e + 10

becomes

5(3) - 3 + 2(9) + 10.

Now, we can simplify the expression further:

15 - 3 + 18 + 10

= 33 + 10

= 43.

Therefore, when c = 5, d = 3, and e = 9, cd - d + 2e + 10 equals 43.
