The vertices of triangle PQR are listed below. P(-5, 3), Q(-13, -3), R(-5, -9)
What is the perimeter of triangle PQR?
A.
32 units
B.
51 units
C.
22 units
D.
48 units

A. 32 units

Step-by-step explanation:

First, we need to find all of the side lengths of triangle using distance formula:

Now, we can calculate length of PQ, QR and PR sides by using their vertices and above formula:

For perimeter we add up the length of all of its sides:

the answer is c. hope this !

step-by-step explanation:

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
