Hi, I need help with my math please

A-H are all true facts except for C which is false. that you have to show and prove are true and false.

Rate of change Purr Island (5 questions name the letter to the workings answer and matched it)  Show constant = 4 cats per year also seen as 40% rate of change. The common factor of 3 is only seen up on year 1 and year 4.   as year 0 shows 2 and 4 does not fit into 2. Explain year 2 that 4 does not fit into 10 on year 2 does not as 2p-6p-10p-14p-18p may change 10p over the last 3 years and CF 3 does not fit into that or any individual (adjacent) proceeding years.

Step-by-step explanation:

The rate of change Meow Island : 3 of the 8 questions is asked to say true to all of them (name the letter to the answer the workings after you wrote this and matched it) Shows it triples = and yes they have common factors of 3 show 2, 6, 18, 54, 162 each share a common factor of 3, draw tree diagrams  or show common factors of 3 and state you compare them to factors of 2    162>2x81   162> 3x27  54>2x27   54>3x18   18>2x9

18>3x6  6>2x3  6>3x2   2>2 population start number this doesnt have a common factor until it is factored into 6 ro show a common factor for 6. This also proves linear change occurs over the 4 years as population 2-156 is a series of  4 changes and underline the >3x numbers.  

2x^2+5x+17

your welcome. : )
