Consider the expression 12a - 7b + 9 - 4a + 3b - 3. Part A : Simplify the expression by combining the like terms. ​ (a)   ​ a ​ (b)   b + ​ 6 Part B: Factor the simplified expression using the GCF. ​ (c)   ( ​ (d)   a - 2b + 3 ) Part C: What is the value of the expression when a = -2 and b = -3? ​ (e)  

• 8

• - 4

• 2

• 4

• 5

• 6

• 2

Answer explanation

The expression can be simplified to 8a - 4b + 6. Factoring the expression gives 2(4a - 2b + 3). When a = -2 and b = -3, the expression evaluates to 8.
