Let the length of the playground be x, then the width is 6 + x.

Area = length * width = x * (6 + x) = 6x + x^2 = 216

Solving the quadratic equation x^2 + 6x - 216 = 0, we have x = 12 or -18

i.e length = 12 and width = 6 + 18 = 18

Can someone help me with this math homework please!

  • Here, t represents time, which is the input of the function, so we know that 10 is the time in minutes.
  • h(t) represents the altitude, which is the output of the function after time, t.

  • So, we need to substitute 10 into 210 -15t in place of t.

  • On simplifying 210 -15(10), we get that 60 is the altitude in feet. So, after 10 minutes, the hot air balloon is at 60 feet.
