Answer:
Step-by-step explanation:
As in the triangle RST,
Because if in a triangle two angles equal one another, then the sides opposite the equal angles also equal one another.
Incenter is obtained by the Intersection of a triangle's three angle bisectors and it is equidistant from the three sides of the triangle.
So, RP and TP are the angle bisectors of ∠R and ∠T respectively.
step 1: distributive property.
step 2: combine like terms.
step 3: subtraction property of equality.
step 4: addition property of equality.
step 5: division property of equality.
hope this helps.

Answer: 13n + 20
Step-by-step explanation:
The cost of each book is $13. That means that if you end up buying "n" books, cost would be:
= Cost of each book * number of books
= 13 * n
= 13n
You would also get charged a flat rate for shipping of $20 which would be added to the above cost to bring a total of:
= 13n + 20
At regular price the 10 candy bars would cost $5.90 (0.59×10=5.90). At the sale price the 10 candy bars cost $4.95 (0.99×5 = 4.95). So you would save $0.95 (as 5.90-4.95 =0.95).
