6. Solve for x. (1 point)
1
2
3

Answer 1

sqrt(2x+3) = sqrt(6x-1)


(sqrt(2x+3))^2 = (sqrt(6x-1))^2


2x+3 = 6x - 1


2x+3-3 = 6x - 1-3


2x = 6x-4


2x-6x = 6x-4-6x


-4x = -4


-4x/(-4) = -4/(-4)


x = 1


So the solution is x = 1

Answer 2

7. Solve for b. (1 point)

Answer 3

sqrt( (b^4)/25 ) = 4


(sqrt( (b^4)/25 ))^2 = 4^2


(b^4)/25 = 16


((b^4)/25)*25 = 16*25


b^4 = 400


sqrt(b^4) = sqrt(400)


b^2 = 20


sqrt(b^2) = +-sqrt(20)


b = +-2*sqrt(5)


So the answer is the second choice
