Answer:
B 3x+2
Step-by-step explanation:
perimiter=2L+2W
P=2(L+W)
if x=width then
P=2(L+x)
P=8x+8
hmm
8x+8=2(L+x)
distribute
8x+8=2L+2x
minus 2x both sides
6x+8=2L
divide both sides by 2
3x+4=L
the length is 3x+4
B is answer
Answer:
y =
+ 2
Step-by-step explanation:
The y-intercept of the line is (0,2)
The slope of the line is
We derive the slope of a line by dividing the change in y by the change in x
So,
= 
y - 2 =
The equation of the line therefore is;
y =
+ 2
