Answer:

Step-by-step explanation:

3x+2y=7

Simplifying

3x + 2y = 7

Solving

3x + 2y = 7

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2y' to each side of the equation.

3x + 2y + -2y = 7 + -2y

Combine like terms: 2y + -2y = 0

3x + 0 = 7 + -2y

3x = 7 + -2y

Divide each side by '3'.

x = 2.333333333 + -0.6666666667y

Simplifying

x = 2.333333333 + -0.6666666667y

A(-3, -1); B(2, -1), C(2, 3)

You can read the length of AB and BC.

|AB| = 5

|BC| = 4

Use the Pythagorean theorem:

$|AC|^2=5^2+4^2\\\\|AC|^2=25+16\\\\|AC|^2=41\to|AC|=\sqrt{41}\\\\|AC|\approx6.4$

The perimeter:

$P=|AB|+|BC|+|AC|\\\\P=5+4+6.4=15.4$
