1.75x – 2
Answer:
1.75×2-2
Step-by-step explanation:
The perimeter of an equilateral triangle, with side length expressed as 1.75x – 2, can be found by tripling the side length expression. Thus, the simplified expression for the perimeter is 5.25x – 6 centimeters.
The question concerns a geometric concept - the perimeter of an equilateral triangle. An equilateral triangle is a triangle in which all three sides are equal. Therefore, to find the perimeter (the distance around the triangle), we simply add up the lengths of all the sides. Since all sides are equal for our triangle, we can multiply the length of one side by three to get the total perimeter.
The given expression for the side length of the equilateral triangle is 1.75x – 2. That's one side. Since an equilateral triangle has three sides of equal lengths, the expression for the perimeter will be 3 times the expression given for one side. Therefore, multiply the expression 1.75x – 2 by 3. So, P = 3(1.75x – 2). By distributing the 3, the simplified expression for the perimeter (P) is P = 5.25x – 6 (centimeters). Thus, the expression 5.25x – 6 simplifies the perimeter of the equilateral triangle in terms of x.
