Y is directly proportional to the positive square root of (x+2)when x=7,y=9. Find y when x=23

15

Step-by-step explanation:

Given: y is directly proportional to when x = 7, y = 9

To find: y when x = 23

Solution:

u and v are said to be proportional if where k is a constant of proportionality.

As y is directly proportional to when x = 7, y = 9,

Put x = 7, y = 9

Put x = 23

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.
