Answer:

AB is A

BC is B

AC is D

Step-by-step explanation:

To find the length of each side, use the formula for the distance between coordinate pairs.

We can find the distance using the distance formula:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

AB

We then substitute (-3,6) as $(x_1,y_1)$ and (2,1) as $(x_2,y_2)$ .

$d=\sqrt{(2--3)^2+(1-6)^2} \\d=\sqrt{(2+3)^2+(-5)^2} \\d=\sqrt{25+25}\\d=\sqrt{50}$

BC

We then substitute (2,1) as $(x_1,y_1)$ and (9,5) as $(x_2,y_2)$ .

$d=\sqrt{(9-2)^2+(5-1)^2} \\d=\sqrt{(-7)^2+(4)^2} \\d=\sqrt{49+16}\\d=\sqrt{65}$

AC

We then substitute (-3,6) as $(x_1,y_1)$ and (9,5) as $(x_2,y_2)$ .

$d=\sqrt{(9--3)^2+(5-6)^2} \\d=\sqrt{(12)^2+(-1)^2} \\d=\sqrt{144+1}\\d=\sqrt{145}$

Answer:

$g(n) = \frac{11}{3} + \frac{5n}{3}$ or g(n) = (11/3) + (5/3)n

Step-by-step explanation:

Equation: $3m - 5n = 11$

To write a formula for g(n) in terms of n, we have to get m seperately.

$3m - 5n = 11$ , add 5n in both sides

$3m - 5n + 5n = 11 + 5n$ , now add

$3m = 11 + 5n$ , now divide both sides by 3

$\frac{3m}{3} = \frac{11 + 5n}{3}$

$m = \frac{11}{3} + \frac{5n}{3}$

Now, replace m with g(n)

$g(n) = m$

$g(n) = \frac{11}{3} + \frac{5n}{3}$
