A rectangular playground has dimensions and area as shown below. Complete the work to find the dimensions of the rectangle.

x(4x + 5) = 450

4x2 + 5x = 450

4x2 + 5x – 450 = 0

(4x + 45)(x – 10) = 0

The rectangle has a width, x, of
, and a length of
.

I think it’s 10 because (x-10)=x=10

9514 1404 393

x = 10width = 10length = 45

Step-by-step explanation:

The remaining work is to identify the values of x that make the factors zero:

4x +45 = 0

  x = -45/4 . . . . negative dimensions are not useful

x -10 = 0

  x = 10

The width is x, so the width is 10.

The length is 4x+5, so the length is 4·10+5 = 45.

The rectangle has a width, x, of 10 and a length of 45.

29. because you will divide each number of months by 12 to find the number of years. which would mean, 5, 12.5, 16, 45, 50, 72.5. which is crazy. anyhow, i think you find the median in the middle. and yea hope your test goes good
