Answer:
If the roots of any equation are equal then it means that their Discriminant = 0
So, b²-4ac = 0
We have given the equation 2x² + kx + 2, where,
a = 2
b = k (we have to find the value)
c = 2
Then, b²-4ac=0
b² - 4(2)(2) = 0
b² - 16 = 0
b² = 16
√16 = 4
Hence the vue of k is 4.

Answer:
57.6 pages
Step-by-step explanation:
First, you need to identify how many minutes are in 3/5 of an hour:
1 hour = 60 minutes
3/5 of an hour = 3/5 of 60 minutes
= 3/5(60)
= 36
So, you need to find out how many pages can be printed in 36 minutes. To figure this out, a ratio can be used:
15 : 24
36 : p
p represents pages in 36 minutes.
Now, you need to solve the ratio by figuring out what you need to multiply 15 by to get 36 and then multiplying that by 24:
15 * 36/15 = 36
36/15 = 2.4
24*2.4
= 57.6 pages
