What is the meaning of s in the speed of 4m / s in the math problem


The meaning of second



The two sides of a triangle are 5cm and 3cm respectively. How short is the third side? How long is the third side?
Remember! And note: the sum of any two sides of a triangle is larger than the third
How long is the longest? Fill in the whole number. Don't forget


If it is an integer, the longest is seven and the shortest is three! Because the third side is greater than 5-3 = 2! Less than 5 + 3 = 8! Because it is an integer, so I'm in high school. It's easy,



If the two sides of a triangle are 12 decimeters and 6 decimeters respectively, how many decimeters may the third side be


Let the third side be a, then:
12-6
