2(3/5n +3) - (2/3n-1)
borishaifa [10]

Hey there! :)


2(3/5n + 3) - (2/3n - 1)


Simplify.


(2 * 3/5n) + (2 * 3) - (2/3n -1)


Simplify.


6/5n + 6 - 2/3n + 1


Add like terms.


(6/5n - 2/3n) + (6 + 1)


Make the fractions have the same denominator by multiplying fraction 1 (6/5n) by 3/3 and fraction 2 (-2/3n) by 5/5.


6/5n * 3/3 = 18/15n


-2/3n * 5/5 = -10/15n


So, our new equation looks like this : (18/15n - 10/15n) + (6 + 1)


Simplify.


8/15n + 6 —> final answer.


Hope this helped! :)

In right triangle ΔABC (m∠C = 90°), point P is the intersection of the angle bisectors of the acute angles. The distance from P
arlik [135]

Answer:

  28 inches

Step-by-step explanation:

The point of intersection of the angle bisectors is the <em>incenter</em>. It is the center of a circle tangent to the three sides of the triangle. The circle has radius 2.

In the attached figure, we have labeled the points of tangency D, E, and F. We know that CE and CF are both of length 2, and we know that the points of tangency are the same distance from an external point where the tangents intersect. That means DA = FA and DB = EB.

The perimeter of the triangle is ...

  P = DA +DB +FA +EB +CF +CE

Using the above relations, this can be written as ...

  P = DA +DB +DA +DB +CF +CE = 2(DA +DB) +2(CE)

We are told that AB is 12 inches, so DA +DB = 12 inches. We also know that CE = 2 inches, so the perimeter is ...

  P = 2(12 in) + 2(2 in) = 28 in

The perimeter of triangle ABC is 28 inches.
