the perimeter is:
4(4x - 6)
Applying distributive property:
4(4x) - 4(6)
16x - 24
Then, the perimeter can also be represented by 16x - 24 because 4(4x - 6) can be simplified to 16x - 24
The equation would be d - 19 = 73. So the zoologist would take the number of deer recorded and subtract it from 19 (since it said 19 fewer deer) and the answer would be 73 (because that is how many deer were recorded a year later. I hope this helps!
X/3=y this is what I got hopes this helps
