Answer:
[1] Addition property of equality
[2] Division property of equality
Step-by-step explanation:
Given the equation, , the following are steps and justification for each step taken:
=> Given equation
Add 6 to both sides
=> addition property of equality [1]
=> simplify
Divide both sides by 4
=> Division property of equality [2]
=> simplify
The justification for the steps taken are:
[1] Addition property of equality
[2] Division property of equality

Question
Find the perimeter of a triangle with vertices A(2,5) B(2,-2) C(5,-2). Round your answer to the nearest tenth and show your work.
perimeter of a triangle = AB+AC+BC
Using the distance formula
AB = sqrt(-2-5)²+(2-2)²
AB = sqrt(-7)²
AB =sqrt(49)
AB =7
BC = sqrt(-2+2)²+(2-5)²
BC = sqrt(0+3²)
BC =sqrt(9)
BC =3
AC= sqrt(-2-5)²+(2-5)²
AC= sqrt(-7)²+3²
AC =sqrt(49+9)
AC =sqrt58
Perimeter = 10+sqrt58

If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up (+1).
If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down (no change).
