Answer:
umm i think it is 5 cm but im not sure
First step: Isolate the term that has x. To do that, subtract 2y from both sides.


Now divide both sides by 3.

Answer:
I think it’s A, Good luck!
Step-by-step explanation:
L=w+2 and 2w+2l=44
substitute equation for length in perimeter equation
2w+2(w+2)=44
2w+2w+4=44
4w+4=44
4w=40
w=10
substitute width into length equation to get length
l=10+2
l=12
a=lw
a=12*10
a=120 cm^2
