Answer :
Answer:
inequality equation :3x ≤ 57
solution: x ≤ 19
Step-by-step explanation:
Length of all sides in an equilateral triangle is same
thus, perimeter of an equilateral triangle is 3x
where x is the side length of an equilateral triangle.
_____________________________________
The perimeter of an equilateral triangle must be at most 57 feet.
It means that that
perimeter must be at most 57 or less that it.
Example perimeter can be 57, 56,52 or any number less than that but it cannot be 57.1, 58 and so on.
Thus, we can also say that
perimeter of an equilateral triangle must be less than or equal to 57 feet. perimeter of an equilateral triangle is give by 3x
where x is the side length
thus writing it in inequality form
3x ≤ 57
=>x ≤ 57/3
=> x ≤ 19
Thus,
inequality equation
3x ≤ 57
solution
x ≤ 19 ( it means length of side can be at-most 19 feet)
