Explanation:</h2>
Remember you need to write complete questions in order to find exact answers. In this way you haven't provided any function, so I'll choose a quadratic function given by:

So we need to find the entire interval at which this function positive. Put another way:

By using graphing tool, we get the graph shown below. As you can see:
- The function decreases from

- The function increases from

- The graph of the function is a parabola that opens up.
But what is really importan in this problem is that:
- The function is positive over the interval

At this interval the function is positive, that is,

Answer: B, C, and D
Step-by-step explanation:
Just did it and got the answers wrong so these are the correct ones
So 48 • 4 would equal 192 so 4 • 2 mins equals 8 mins and then you have 8 more books to unpack so 48 divide by 8 equals 6. So the answer would bc (8 mins and 6 second)
Answer:
The wide of river is 
Step-by-step explanation:
In this problem we know that
Triangles DEG and DEF are congruent by ASA (Angle-Side-Angle) Congruence
therefore
EG=EF
