Question

17

i already did the test

Answer 1

17

Explanation:

I believe the answer is 17.

Simplify

17

=17

Now,

Consider point O at zero on the number line.

Mark a point A such at number 4 such that OA= 4

Draw a perpendicular AB at point A of unit length.

Join AB

Taking radius of length AB draw an arc to intersect the number line at C.

Finally, OC=\sqrt{17}

Thus proving the answer is 17 or
`√(289) = 17`
