Answer:

Step-by-step explanation:

The central angle of the two arcs (marked as 40 degrees each) means that <HPN = 80. The central angle = the arc measurement.

Now here's the tricky part. Any point on the circumference of a circle that has the same measurement using NH as a chord = 1/2 the central angle.

So <HRN = 1/2 the central angle

Since the central angle = 80, then 1/2 of it = 40

<HRP = 40 degrees because PR is a part of RN

Find the sum of 12a + 7b, −6a − 9, and 14a − 12b.

Ivan

The answer is: [A]: " 20a − 5b − 9 " .
______________________________________
Explanation:
_______________________________________________
(12a + 7b) + (−6a − 9) + (14a − 12b) =

12a + 7b + 1(−6a − 9) + 1(14a − 12b) =

12a + 7b + (1*-6a) + (1*-9) + (1*14a) + (1* -12b) =

12a + 7b − 6a − 9 + 14a − 12b = ?

Combine the "like terms:

12a − 6a + 14a = 20a ;

7b − 12b = - 5b ;

and then we have "-9" ;
_____________________________________________________
So, write as: " 20a − 5b − 9 " ; which is: Answer choice: [A].
