I think your question is lack of information:
After one hour, the hare had finished 2/3 of a 100-yard race. In that same time, the tortoise had finished 42 3/4 yards. How much farther had the hare run than the tortoise?
Step-by-step explanation:
In one hour:
- The hare: 2/3 of 100-yard race = 200/3
- The tortoise: 42 3/4 yards = 171/4
How much farther had the hare run than the tortoise = 200/3 - 171/4 ≈23 yards.
We have that
x²<span>+2x=17
</span><span>Group
terms that contain the same variable
</span>(x²+2x)=17
<span>Complete
the square. Remember to balance the equation
</span>(x²+2x+1)=17+1
Rewrite as perfect squares
(x+1)²=18
x+1=(+/-)√18
x=(+/-)√18-1
x1=√18-1----> 3.24
x2=-√18-1----> -5.24
the answer is
the option

4.) 3.24, –5.24</span>
The minimum of a graph is where the curve of the parabola is at its lowest point. On this graph the minimum looks to be at (-2, -2), but make sure that is where the curve is lowest.
