Sqrt(5u + 2) = sqrt(3u + 14)
Square both sides to clear the square root.
5u + 2 = 3u + 14
subtract 3u from both siides
2u + 2 = 14
subtract 2 from both sides
2u = 12
divide both sides by 2
u = 6
When you square a square root you MUST check the solution.
sqrt(5*6 + 2) = sqrt(3*6 + 14)
sqrt(32) = sqrt(32)
Answer:
local calls per 1 long distance call.
Step-by-step explanation:
Local calls 
Long distance calls 
For 20 long distance calls local call ![=35 For 1 long distance calls local call [tex]=\frac{35}{20} =\frac{7}{4}](https://tex.z-dn.net/?f=%3D35%20%3C%2Fp%3E%3Cp%3EFor%201%20long%20distance%20calls%20local%20call%20%5Btex%5D%3D%5Cfrac%7B35%7D%7B20%7D%20%3D%5Cfrac%7B7%7D%7B4%7D)

Step-by-step explanation:
The given equation is

The given inequality is

A point will contained in solution set if the above inequality satisfied by that point.
Check the point (0,-3),


This statement is false, therefore option a is incorrect.
Check the point (-3,0),


This statement is false, therefore option b is incorrect.
Check the point (3,3),


This statement is true, therefore option c is correct.
Check the point (-3,-3),


This statement is false, therefore option d is incorrect.
