The relationship between (126+9) is that you are just adding and for (126+9)/2 you are still adding but after you find your answer you then divide by 2

The answer would be quadratic trinomial

Answer for 2: his profit would be $2.88 explanation: you have to first multiply 72 and 0.12 together to get $8.64 once you do that you know how much money the shopkeeper made from selling the candy bars individually. so you have to do 8.64-5.76=2.88 hope that ; )answer for 3: yeah i’m sorry i have no idea what number 3 is. i’m sorry i couldn’t with that.
