the side of a triangle ae 3x+2,6x-1, and 7-x. espress the perimeter of the triangle in terms of x.
just add them up
To find the perimeter of a triangle given the lengths of its sides, we simply add up the lengths of all three sides.
Given the lengths of the sides of the triangle, which are 3x+2, 6x-1, and 7-x, we can express the perimeter in terms of x by adding these three lengths together.
Perimeter = (3x+2) + (6x-1) + (7-x)
To simplify this expression, we can combine like terms.
Perimeter = 3x + 2 + 6x - 1 + 7 - x
Rearranging the terms:
Perimeter = (3x + 6x - x) + (2 - 1 + 7)
Combining like terms:
Perimeter = 8x + 8
Therefore, the perimeter of the triangle in terms of x is 8x + 8.
