Answer:

Step-by-step explanation:

(6/5)√x = x - 6

(36/25)x = x² - 12x + 36

0 = x² - 13.44x + 36

x = (13.44 ± √(13.44² - 4(1)(36))) / (2(1))

x = (13.44 ± 6.052569702...) / 2

x = 3.69371... zebras

or

x = 9.74628... zebras

In either case we have some odd fractions of zebras hanging around. This makes me highly suspect that the question is misreported

Tina wants to decorate a rectangular picture frame measuring 18 w 14 tall she has 4 ft of rope dies she have enough rope
igor_vitrenko [27]

Tina does not have enough rope to decorate the frame

Step-by-step explanation:

Tina wants to decorate a rectangular picture frame

  • The width of the frame is 18 inches
  • The length of the frame is 14 inches
  • She has 4 feet rope

We want to know if she has enough rope or not to decorate the frame

∵ The frame is in the shape of the rectangle

- The length of the rope must be equal the perimeter of the frame

∵ The perimeter of a rectangle = 2 length + 2 width

∵ The length = 14 inches

∵ The width = 18 inches

∴ The perimeter of the frame = 2(14) + 2(18) = 28 + 36 = 64 inches

∵ The length of the rope is 4 feet

∵ 1 foot = 12 inches

∴ The length of the rope = 4 × 12 = 48 inches

∵ 48 < 64

∴ The length of the rope is less than the perimeter of the frame

∴ Tina does not have enough rope

Tina does not have enough rope to decorate the frame
