Will grant what is the value of x, radical (2x + 1) = 13? a) x = 6 b) x = 6.5 c) x = 83.5 d) x = 84

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!

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
