Using the equation
, are both x = 2 and x = 9 solutions or are one/both of them extraneous solutions? Explain.​

Given:

The equation is:

To find:

Whether and both are solutions or one/both of them extraneous solutions.

Solution:

We have,

Subtract 5 from both sides.

Taking square on both sides, we get

Splitting the middle term, we get

Now, substitute in the given equation.

This statement is false because . So, 2 is an extraneous solution.

Substitute in the given equation.

This statement is true. So, 9 is a solution of given equation.

Therefore, 2 is an extraneous solution and 9 is a solution of given equation.

answer: the sun

explanation:

water cycle describes the evaporation of water from earth's surface, formation of clouds and precipitation water back onto the surface of earth. seventy percent of the earth is covered with water in the form of seas and oceans. the heat of the sun causes the evaporation of water from the surface of the ocean. the water vapors rise and condense to form water droplets. the collection of these water droplets form clouds which rain down again.

the evaporation of the oceans surface water as part of the water cycle is caused by the sun
