Question

solve for x. sqrt--(4x+1) +1=40

Answer 1

x=380

Answer 2

\[is \it \sqrt{4x+1} +1 = 40....?\]

Answer 3

subtract 1 from the both sides &:
\[4x+1=39^{2}\]
4x=39^2 -1
solve it for x, please... OK?

Answer 4

x=1520/4
x=380

Answer 5

\[\sqrt{4x+1}+1=40\]
\[\sqrt{4x+1}=40-1=39\] Squaring both sides
\[4x+1=1521\]
4x=1520
x=380
