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
I added you :) I hope you don’t mind
Z-score for 80% to pass = -0.842.
-60.624 = X - 426
X = 426 - 60.624
X = 365
Therefore the required passing score is 365.
