A. 10p
b. 10p-75
c. 10p-75<span>≥50</span>
You must remember that a polynomial is written like so...
ax^2 + bx + c
In this case...
a = 1
b = 10
c = 21
To factor you must find two numbers who both add up to b (10) AND multiply to c (21)
3 + 7 = 10
3 * 7 = 21
so...
(x + 3 )(x + 7)
Hope this helped!

Answer:
4
Step-by-step explanation:
360 deg = 20
1 deg = 20/360
72 deg = 20/360 * 72 = 4
The formula of a volume of a pyramid:
B-area of a base
h-height
Substitute:
Find the least common multiple of 14 and 16.
14 = 7*2 ----> multiply by 8 ----> 8*7*2 = 112
16 = 8*2 ----> multiply by 7 -----> 7*8*2 = 112
The LCM is 112. This means it will be 112 minutes before they dump water at the same time.
112 min = 1 hr 52 min
3:20 + 1hr 52 min = 5:12
For the next time, add another 112 minutes
Answers: 5:12 PM and 7:04
