Answer:
im guessing 12 because 12x12=114, and since the garden is a square, we length/with has to be the same number.
Step-by-step explanation:
Answer: y=12/5 and P=120
Step-by-step explanation:
Set (10y-4)=(5y+8) which makes y=12/5
Substitute y in for both PS and QR to get 20 and 20
If PQ=2PS, then 2(20)=40. Do the same for SR to also get 40
40+40+20+20=120
I also do not understand this question. Help please
![x+y=159\\ \underline{x-y=3}\\ 2x=162\\ x=81\\\\ 81-y=3\\ y=78](https://tex.z-dn.net/?f=x%2By%3D159%5C%5C%0A%5Cunderline%7Bx-y%3D3%7D%5C%5C%0A2x%3D162%5C%5C%0Ax%3D81%5C%5C%5C%5C%0A81-y%3D3%5C%5C%0Ay%3D78)
These numbers are 81 and 78.
