The width of a rectangle is 21 cm. The perimeter is at least 316 cm. Write an inequality that represents all possible values for the length of the rectangle. Then solve the inequality

Step-by-step explanation:

Length=x cm

width= 21 cm

Equation of perimeter of rectangle is 2 x (length+width)

2x (21+x) large and equal (> =)316

x> = 137

answer: 230 miles ( vote ! )

step-by-step explanation:

180.39 minus 17.99 equals 162.4

then divide 162.4 by .80 to get 230

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
