7+2x
You start off with $7 for 1 dog and for every other dog you bring is $2 more
-4/7 (decimal form (.571))
The longer side is at first 7cm and the shorter is 2cm.
So since 7cm(the longer side)×5=35cm then the shorter side(2cm) multiplied by 5 should give you the right answer.
<span>i believe it should be 17 19 and 23 but i could be wrong. </span>
Im too sure but i think its y=-2x+2
