Answer 3

^^^ d it is.

Answer 4

okay ranga - I was going to work it out

Answer 5

B is the correct answer...

Answer 6

sqrt(6x +4) = 8

Square both sides
6x + 4 = 64

Subtract 4 from both sides
6x + 4 -4 = 64 -4
6x = 60

divide both sides by 6
6x = 60
x = 10

That is answer 'd'

Answer 7

@Haseeb96 The first step is to square both sides to get rid of the square root.
The first step in b) is to take square root on both sides!

Answer 8

answer 'b' starts with take the square root of both sides
sqrt(6x +4) = 8
which becomes
(6x +4)^.25 = sqrt(8)
