The nature of the roots can be determined by the determinant of the equation. The determinant is:
b² - 4ac
If this is positive, there are two roots
If this is 0, there is only one root
If this is negative, there are complex roots
3/4n+1/4n: 1n and 8-12: -4 so it would be n-4
Answer:
The length is <u>8</u> ft.
The width is <u>2</u> ft.
Step-by-step explanation:
A = l*w
l = w + 6
16 = w(w + 6)
16 = w^2 + 6w
w^2 + 6w - 16 = 0
(w + 8)(w - 2) = 0
w = -8ft or 2ft
Since lengths cannot be negative in reality, <u>w = 2ft</u>.
l*2 = 16
<u>l = 8ft</u>

Answer: 24</h3>
The first coefficient is 8 and the constant term is 3.
p = 8 and q = 3 leads to p*q = 8*3 = 24.
Number of red marbles/total number of marbles
35/(35+8+7)
35/50
7/10
The probability is 7/10
