Consider the expression -4b + 8c + 12. Part A: Factor the expression using the GCF by dragging and dropping the numbers to the correct locations. ​ (a)   (​ (b)   b + ​ (c)   c + ​ (d)   ) Part B: What is the value of the expression when b = 2 and c =1? ​ (e)  

• 4

• -1

• 2

• 3

• 12

• -4

• 20

• -3

Answer explanation

The expression -4b + 8c + 12 can be factored as 4(-b + 2c + 3). When b = 2 and c = 1, the expression evaluates to 4(-2 + 2 + 3) = 4(3) = 12. Therefore, the correct answer is 12.

Part B: What is the value of the expression when b = 2 and c =1?

​ (e)  

• 4

• -1

• 2

• 3

• 12

• -4

• 20
