2.120 kg and 2.12 kg are inherently the same, the zero on 2.120 is actually slightly unnecessary (unless a function asks for a certain tenth's or thousands place to be defined). This problem asks you to write an equation representing this information, I believe the easiest way to do this would be

2.120 kg = 2.12 kg

false

step-by-step explanation:

4y - 6 + 4y^2 - 9

after simplifying

4y -15 + 4y^2

it contains 3 terms

answer: you need to organize this better it does not make sense.
