Answer:
B
Step-by-step explanation:
x²+2x=19 add 1 to both sides which gives you x²+2x+1=20
x²+2x+1 is the same as (x+1)²
Therefore (x+1)²=20
Answer:
It's about 6,111 kids per second.
Step-by-step explanation:
1 hour = 60 minutes
1 minute = 60 seconds
60*60=3600
1 hour = 3600
hourly rate -> 22,000,000 kids/hr
secondly rate -> 22,000,000/3600 ≈ 6,111
secondly rate -> 6,111 kids/second
So you do 93 times 60 because it said you have to do 6 ten times and that equal 5580

Answer: (0,5)</h3>
This is because the x coordinate is 0. For any y intercept, the x coordinate is always 0 as this indicates the point is on the y axis.
Contrast this with something like (9,0) and we see that y = 0 indicating this point is an x intercept (it is on the x axis).
