what is the perimeter of this rectangle?

a) 2(x^2-x^1)+2(y^2-y^1)

b) (x^2-x^1)(y^2-y^1)

c) radical: 2(y^2-y^1)(x^2-x^1)

d) 4 radical: (y^2-y^1)^2(x^2-x^1)^2

e) 4(y^2-x^1)(x^2-y^1)

idk

step-by-step explanation:

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y

0       8
