Explanation:</h2>
Hello! Recall that you need to write complete questions in order to get good and precise answers. However, I'll try to explain this problem in a general way. The definition of polynomial functions states:

Suppose we have the following polynomial function:

If
is a factor of this polynomial function, we can write
as:

In whose case:

Evaluating 

So in conclusion:
The graph is shown below and is consistent with our conclusion.

Answer:
10.5.
Step-by-step explanation:
By similar triangles:
IJ / 21 = 8 /(8+8) = 1/2
IJ / 21 = 1/2
IJ = 1/2 * 21
= 10.5.
