We can use the distance formula to calculate perimeter: 
= Distance
From A to B: √232
From B to C: 10
From C to A: √52
10 + √232 + √52 = 10 + 2√58 + 2√13
Perimeter = 10 + 2√58 + 2√13 units
For Area we can use matrices, but since one of the sides is horizontal, we can just calculate with distance formula and area of triangle formula.
The area of a triangle formula is 1/2(h x b)
h=height
b=base
So the height is 6 and the base is 16. (I graphed it.)
16 * 6 = 96 96/2 = 48 Area: 48 square units.
Answer:
Slope of line 1 = 3
Slope of line 2 = 3
Slope of line 3 = -1/3
Line 1 and 2 are parallel
Line 1 and 3 are perpendicular
Line 2 and 3 are perpendicular
Step-by-step explanation:
Find the slope of each line by using this equation:
lines are parallel if they have the same slope and line are perpendicular in they have opposite reciprocal slopes. (-1/3 is the opposite reciprocal of 3).

Answer:
The correct answer is x = 7.
Step-by-step explanation:
To solve this problem, our first step is to use the distributive property on the left side of the equation. This is modeled below:
-5x + 10 = -25
Next, we should subtract 10 from both sides of the equation.
-5x = -35
Finally, we should divide both sides of the equation by -5 to get the variable x alone on the left side of the equation.
x = 7
Therefore, the answer is x = 7.
