The length is 3 times the width. The area is 36 square feet. Write an expression for the length, l, of the banner in terms of the width, w.
Replace l in the area formula with the expression you wrote above.
Solve the quadratic equation to find the width of the banner.
What is the width of the banner?
What is the length of the banner?

step-by-step explanation:

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct
