(if u don't help and just want points i will report)

Answer 1

The answer is 20-1/4x+4/3y

Answer 2

Answer:
`20-(1)/(4)x+(4)/(3)y`

================================================

Work Shown:

`P = 2L + 2W\\\\P = 2\left(10-x+(4)/(9)y\right) + 2\left((7)/(8)x+(2)/(9)y\right)\\\\P = 2\left(10\right)-2x+2\left((4)/(9)y\right) + 2\left((7)/(8)x\right)+2\left((2)/(9)y\right)\\\\`

`P = 20-2x+(8)/(9)y + (14)/(8)x+(4)/(9)y\\\\P = 20-2x+(8)/(9)y + (7)/(4)x+(4)/(9)y\\\\P = 20+\left(-2x + (7)/(4)x\right)+\left((8)/(9)y+(4)/(9)y\right)\\\\`

`P = 20+\left(-(8)/(4)x + (7)/(4)x\right)+\left((8)/(9)y+(4)/(9)y\right)\\\\P = 20+\left((-8+7)/(4)x\right)+\left((8+4)/(9)y\right)\\\\P = 20-(1)/(4)x+(12)/(9)y\\\\P = 20-(1)/(4)x+(4)/(3)y\\\\`
