6 0

Answer:


Step-by-step explanation:

x^2+120=0 can be rewritten as x^2 = - 120.  Taking the square root of both sides, we get x = plus or minus i*√120 = plus or minus i*√4√30, or

x = plus or minus i*2√30

So the correct answer choice here is "None of the above."

Maru [420]

The distance between starting and ending point is 34 miles.

Step-by-step explanation:

Given,

Car moves 16 miles to north then 30 mile to east.

It forms a right angle triangle.

The straight line distance from starting to ending point represents hypotenuse.

To find the distance between starting and ending point.

Formula

By <em>Pythagoras theorem,</em>

h² = b²+l² where h is the hypotenuse, b is base and l is the another side.

Taking, b=16 and l=30 we get,

h² = 16²+30²

or, h = \sqrt{256+900}

or, h = \sqrt{1156} = 34

Hence,

The distance between starting and ending point is 34 miles.
