Which of the following is a radical equation? O x+ √5 - 12.
O x2 = 16
O 3+x7 - 13
0 7 √x = 14

7√x = 14

Step-by-step explanation:

A radical equation is an equation in which a variable is under a radical. Out of all the equations, the only answer with x under the radical (square root symbol) is 7√x = 14.

Brandon is 9 years old and Michael is 36 years old. (Pls give Brainliest)

Explanation:

Consider Brandon's age to be x.

Michael's age will then be 4x as well as x+27 (since he is not only 4 times as old as Brandon but also 27 years older than him).

Well, if Michael is not an extraterrestrial being that defies physics, then he cannot have 2 ages simultaneously which leads us to believe that 4x has to be equal to x+27.

Set up the equation:

4x = x+27  (Subtract x from both sides)

3x = 27      (Divide both sides by 3)

x = 9

Brandon is 9 years old and Michael is 36 years old.
