Answer:
No real solutions.
Step-by-step explanation:
x² + 6x + 10 = 0
a = 1
b = 6
c = 10
D = b² - 4ac = 6² - 4*1*10 = 36 - 40 = - 4
- 4 < 0,
so this equation has no real solutions.

Answer: 9,979,200</h3>
This is one single number. It's just a bit under 10 million
Delete the commas if necessary.
==================================================
Explanation:
If we could tell the repeated letters apart, then there would be
11*10*9*8*7*6*5*4*3*2*1 = 39,916,800
different ways to scramble up the letters.
However, we have 2 copies of b and 2 copies of i
So we have to divide by 2*2 = 4 to correct this overcounting
(39,916,800)/4 = 9,979,200
We let y equal to the elevation above sea level so that the elevation of the rock climber after x minutes of climbing would be:
y = 2x + 50
His initial height can be calculated when x is equal to zero it is when the climber is not yet climbing. Therefore, the rock climber'sinitial height above sea level would be 50 meters.
33 = p -6.71
To solve for P, add 6.71 to each side:
p = 33 + 6.71
p = 39.71
The second choice is correct.
20. Using absolute value, make (-10) turn into 10 and do 10 + 10 = 20
