Answer:
{x | x R, x > -5}
Step-by-step explanation:
Given:
Add 5 both sides, we get
Therefore, the solution is 
where, x is a real number.
So, {x | x R, x > -5} is the correct answer.
Answer:
The three sides are 27 feet, 15 feet, 13 feet
Step-by-step explanation:
Let second side of a triangle be = a
Let one side be 12 feet shorter than the second side = (a - 12)
Let the third side be 2 feet shorter than the second side= (a - 12) - 2 =(a - 14)
Perimeter of triangle = Sum of length of all 3 sides
55 = a + (a - 12) + (a - 14)
55 = a + a + a - 12 - 14
55 = 3a - 26
55 + 26 = 3a
81 = 3a
a = 27
Length of one side, a - 12 = 27 - 12 = 15 feet
Length of second side, a = 27 feet
Length of third side, a - 14 = 27 - 14 = 13 feet
