First compute the perimeter of the pool:
(21+33)*2=108 foot.
Since the material cover 232 ft^2, then it is sufficient to divide the above number over the length of the border like this:
232/108=2.1
The trip can be 2.1 ft in wide.
82/4+20-15
82:4=20.5
20.5+20=40.5
40.5-15=25.5
The explanation is on the board just tell me if you have questions
B or D, I forgot whether the open circle or the circle is the equal to one, if I had to guess I'd say B
Step-by-step explanation:
x² - 2x - 48
= (x - 8)(x + 6)
Coefficient of x² is positive, => Happy shape curved upwards
Hence x < -6 or x > 8.
