The lengths of the sides of a triangle are x, x+1 and 7 centimeters and the perimeter of the triangle is 56 centimeters. The equation is x + (x+1) = 56 what is the length of the longest side of the triangle

the longest side is 25

Step-by-step explanation:

the equation would be x + x+1 + 7 for the 3 sides of the triangle

x + (x+1) + 7=56

combine like terms

2x+8 = 56

subtract 8 from each side

2x = 48

divide by 2

x = 24

the sides are

x=24

x+1 = 25

7

the longest side is 25
