Margaret is planning a rectangular garden it’s length is 4 feet less than its width it’s area is 170 ft.² what are the dimensions of the garden

11.19ft * 15.19ft

Step-by-step explanation:

Width = x

Length = x-4

Area = 170ft2

Area of a rectangle = Length * Width

                 170ft^2   = (x-4) * x

                  x(x-4) = 170equation(1)

                  x^2-4x-170 = 0equation(2)

Using the quadratic equation(for equation 2),

      -b+-sqrtb^2-4ac/2a

from equation(2): a=1x=1

                              b= -4

                              c= -170

thus, x= 4 + sq.rt696/2 = 4 +26.38 =30.38/2=15.19

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.

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5
