ANSWER

EXPLANATION
The end points of the segment are:

and

The box represents the midpoint of the two points.
Using the midpoint formula;

We substitute the end points of the line segment to obtain,

This simplifies to:

We convert back to mixed numbers to get,

The correct choice is B
Answer:
The standard form of the expression (5a+2)(a+4) is
.
Step-by-step explanation:
Here, the given expression is (5a+2)(a+4).
Now, (5a+2)(a+4) = 5a(a+4) + 2(a+4)
= 
= 
or, 
Also, Standard Quadratic form is 
Hence, the standard form of (5a+2)(a+4) is
.
Answer:
are this the answers?
Step-by-step explanation:
Parenthesis, then exponents, then subtraction.
The number of ways when the choice is not relevant is 1716
<h3>How to determine the number of ways?</h3>
The number of letters are:
Letter, n = 13
The letter to choose are:
r = 6
<u>Relevant choice</u>
When the choice is relevant, we have:

This gives

Evaluate
Ways = 241235520
Hence, the number of ways when the choice is relevant is 1235520
<u>Not relevant choice</u>
When the choice is not relevant, we have:

This gives

Evaluate
Ways = 1716
Hence, the number of ways when the choice is not relevant is 1716
