Answer 1

To evaluate the given expression, substitute the values of c and d:

c ÷ d + d^2 + 2c ÷ 2 + 2

When c = 20 and d = 4:

20 ÷ 4 + 4^2 + 2(20) ÷ 2 + 2

Simplify the expression according to the order of operations:

5 + 16 + 40 ÷ 2 + 2

Perform the divisions and multiplications before addition/subtraction:

5 + 16 + 20 + 2

Perform the addition:

43 + 2 = 45

Therefore, when c = 20 and d = 4, the given expression evaluates to 45.
