Answer:
missing side: 2x+3y
Step-by-step explanation:
Since the given 2 sides are x-y and x+y and P=4x+3y,
x-y+x+y= 2x
4x+3y-2x= 2x+3y
Check:
x-y+x+y+2x+3y= 4x+3y

Answer: 11
Step-by-step explanation:
If 15 workers can paint 18 houses in 24 days, how many days will 40 workers take to paint 22 houses?
--------------
# of days are inversely related to # of workers and directly related
to # of houses.
--------------
d = kh/w
---
Solve for "k" using "15 workers can paint 18 houses in 24 days"
24 = k*18/15
k = 15*24/18 = 15*(4/3) = 20
--------------
Equation:
d = 20h/w
---
Solve: How many days will 40 workers take to paint 22 houses?
d = 20*22/40
d = 11 days
