Pretty sure it’s 4 idk tho this is a tough one. Hahahaha
L=length, w=width
l=2w+5
2l+2w=34
2l=4w+10 [here I just multiplied the first equation by two]
4w+10+2w=34 [substitute 4w+10 for 2l]
6w=24, w=4
remember l=2w+5 so l=2(4)+5=13
Answer: The length is 13.
18 + 2y + 6 = 36
2y = 12
y = 6
Since RS bisects AB,
25 - 3x = 2y + 5
25 - 3x = 2(6) + 5 = 12 + 5 = 17
3x = 25 - 17 = 8
x = 8/3
