WILL GRANT BRAINLIST!!

What is the value of x, when... radical (2x + 1) = 13?

A) x = 6
B) x = 6.5
C) x = 83.5
D) x = 84

Answer 1

The answer is A, x=6

Answer 2

$\sqrt{2x+1} =13$

To get rid of the radical square both sides of the equation:

2x + 1 = 169

Combine like terms by subtracting 1 to both sides

2x + (1 - 1) = 169 - 1

Isolate x by dividing 2 to both sides

2x/2 = 168/2

x = 84

Hope this helped!
