Darko found the distance between points a(3,-4) and b(-1,3) his work is shown below

We know that in two dimensional co-ordinate geometry, the distance,d, between any two points and is given by the formula:

We will use the above formula that Darko must have used to find the distance between the two points A(3,-4) and B(-1,3). In this case: and .

Thus, the distance,

Therefore, the distance between the given points A(3,-4) and B(-1,3) is: or 8.06 (approx).

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.

step-by-step explanation:

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !
