the number of items bought if the cost of each item is (x + 2).​

Answer 1

Answer:

=>10.

Step-by-step explanation:

=> Given:

=> Total cost would by (2x²+12x+16)

=> 4+12x+16

=> 12x+16+4

=> 12x = 16+4

=> 12x+20

=> x= 20-12

=> x =8

Each item = (x+2)

=> x = 2

so (x+2) is 8+2 which is 10.

This is your answer..
