Answer:
9/a
Step-by-step explanation:
8/a - 6/a + 7/a
Since the denominators are the same, we can add the numerators
8-6+7 =9
Then put it over the common denominator a
9/a
Answer: THIRD OPTION.
Step-by-step explanation:
For this exercise you need to use the formula for calculate the distance between two points. This is:
Given the following points:
and 
You can identify that:
Knowing these values, the next step is to substitute them into the equation for calculate the distance between two points and then evaluate.
Therefore, the distance between and is:
ABC=DBC
(This will probably be a way more complex explanation than you need but it’s what I did.)
Okay so you know B=B because they’re both right angles. You know A=D because of the isosceles triangle theorem- if two sides of a triangle are congruent, then the angles opposite those sides are congruent. That leaves C=C. If B=B and A=D and all triangles add up to 180 degrees, C and C need to be the same.
<span>This construction uses Constructing the Perpendicular Bisector of a Line Segment to find the midpoints of the sides.
</span>To construct a midsegment, find the midpoint of two sides. This can be done by drawing a perpendicular bisector on one side of the triangle<span>.

I hope my answer has come to your help. God bless and have a nice day ahead!
Yes it is a arithmetic sequence this is because you are adding 8 to each number to get the result of the next number
