A RECTANGLE WITH A LENGTH OF X + 5 HAS A PERIMETER OF 4X + 14. a. Write the expression for the width of the rectangle in terms of x.

b. Suppose the perimeter of the rectangle is 42 inches. What are length and width of the rectangle?

c. Write the expression for the area of the rectangle in terms of x.

d. Find the area of the rectangle when x = 7 in.

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a

c) the median for town a 30" is greater than the median for town b 25"

step-by-step explanation:

town a, median = q2 = 30

town b, median - q2 = 25

so the median for town a 30" is greater than the median for town b 25"

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
