Length of the shortest side is 40 feet
Step-by-step explanation:
- Step 1: Let the length of the shortest side of the triangle be x. Then the length of the other sides are 2x and x + 14 and perimeter = 174 feet
Perimeter of a triangle = Sum of its sides
⇒ 174 = x + 2x + x + 14
⇒ 160 = 4x
⇒ x = 40 feet
Solve each
5x+7>-8
minus 7 both sides
5x>-15
divide by 5
x>-3
3x+7≤19
minus 7 both sides
3x≤12
divide by 3
x≤4
so we got
x>-3 AND x≤4
and means that the solution set must satisfy both at once
so x is bigger than -3 and less than or equal to 4
so between -3 and 4 including 4
-3<x≤4
last one
