The legth of a rectangrle is twice its width the perimeter of the rectangle is 166 feet

P=2(L+W)
P=166
166=2(L+W)
divide by 2
83=L+W

length is tiwce width
L=2W
subsitutte 2W for L

83=L+W
83=2W+W
83=3W
divide both sides by 3
83/3=W
subsitut back

L=2W
L=2(83/3)
L=166/3

the length is 166/3 ft and width is 83/3ft
length is about 55.33ft and width is about 27.66ft

The graph for y = (1/2)x + 1 is C.

Step-by-step explanation:

y = (1/2)x + 1

This line has a slope of 1/2.  That is a positive line, so option A is incorrect.  It also has a y-intercept of 1.  The value of y when x is zero is 1.  There are two graphs in which the line intersects (0,1):  A and C.  But A has already been rejected, so it must by Graph C:  

Double check this to see if the slope is 1/2.  Does y increase by 1/2 for every step of 1 on x?  Graph C:

x     y

-2     0

-1      1/2

0       1

+1      1 1/2

+2      2

Yes:  Y increases by (1/2) for every x increase of 1.

The graph for y = (1/2)x + 1 is C.
