Answer:
D
Step-by-step explanation:
solve square root of 3x plus 1 = 4:
D is correct and results in 3x + 1 = 16; after this we subtract 1 from both sides and end up with 3x = 15, or x = 5.
Answer:
To solve this equation we have to first remove the square root from LHS and to remove the square we have to square both sides.
Step-by-step explanation:
The quadratic equation which violet has to solve is given as
[tex]\sqrt{3x+1}=4[/tex]................(1)
Step 1
To solve this equation we have to first remove the square root from LHS and to remove the square we have to square both sides.
After squaring both the sides we got following equation
[tex]3x+1=16[/tex]....(2)
Step 2
now subtract 1 from both sides to remove 1 from LHS
so we will get the following equation
[tex]3x=15[/tex]....(3)
Step 3
Now divide by 3 from both sides to remove 3 from LHS
Therefore,
[tex]x=\frac{15}{3}[/tex]
[tex]x=5[/tex]
