Question

Solve for x.
the square root of 3x-1=7
the square root of 3x+1=7







What is the root? If there is no root, choose none.

16
none
12
16 2/3

Answer 1

\[\sqrt (3x - 1)= 7\]

Answer 2

Is this what it looks like?

Answer 3

I'm just asking if the sqrt is just over the 3x or also extends to 1

Answer 4

Okay that works.

Answer 5

\[\sqrt (3x - 1)= 7\]
Square both sides
\[3x - 1 = 49\]
Add 1 to both sides
\[3x = 50\]
Divide both sides by 3
\[x = 16.67\]

Answer 6

16
none
12
16 2/3 these are the only options

Answer 7

\[\sqrt (3x + 1) = 7\]
\[3x + 1 = 49\]
\[3x = 48\]
\[x = 16\]

Using the same logic

Answer 8

Yeah .67 is 2/3
