Evaluate the expression.
1. 7 + 4(–3)2(6) + 6
2. 63 – 2(6 – 4)
3. Evaluate the following expression if x = 12, y = 4, and z = 4.
4. Evaluate the following expression if a = 9, b = 6, and c = 7.
3c + bc – 2a
Evaluate the expression. Show each step.
5. 4 + 5(18 – 32) + 4
a. 4 + 5(18 – 32) + 4
= 4 + 5(15) + 4
= 4 + 75 + 4
= 83
b. 4 + 5(18 – 32) + 4
= 4 + 5(18 – 9) + 4
= 4 + 5(9) + 4
= 4 + 45 + 4
= 53

c. 4 + 5(18 – 32) + 4
= 4 + 5(18 – 9) + 4
= 4 + 5(9) + 4
= 9(13)
= 117
d. 4 + 5(18 – 32) + 4
= 9(18 – 9) + 4
= 9(9) + 4
= 81 + 4
= 85
