The length of a rectangle is twice the width. The perimeter is 18 inches.

Breadth = 3 ; Length  = 6

Step-by-step explanation:

Let the width be 'x'

Length = 2x

Perimeter = 18

Perimeter formula for rectangle = 2 ( length + breadth )

Substitute:

2 ( 2x + x ) = 18

2 ( 3x ) = 18

3x = 9

x = 3

Therefore, the width is 3.

The length is 2x = 2(3) = 6.

To check, find the perimeter:

2 ( 3 + 6 )

= 2 ( 9 )

= 18.

The perimeter is correct, therefore our answer for the width and breadth of the rectangle is correct.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
