Answer:

  x = 23; not extraneous

Step-by-step explanation:

A solution is extraneous if it does not satisfy the original equation. Extraneous solutions can sometimes be introduced in the process of solving radical and rational function equations.

<h3>Solution</h3>

Squaring both sides of the given equation, we get ...

  √(3x +12) = 9

  3x +12 = 81 . . . . . . square both sides

  x +4 = 27 . . . . . . . divide by 3

  x = 23 . . . . . . . . . . subtract 4

<h3>Check</h3>

There is only one solution, and it satisfies the equation:

  √(3×23 +12) = √81 = 9

The solution x = 23 is not extraneous.

Use the information given in the diagram. Tell why UW=UW and UVW=WXU.
kow [346]

Answer:

The correct option is D.

Step-by-step explanation:

Given the figure in which UV=XW, UX=VW and ∠UXW=∠UVW.

We have to tell why UW=UW and ∠UVW=∠WXU.

As the reflexive property of equality states that a value is equal to itself.

Hence, in quadrilateral UVWX,

UW is equal to UW by reflexive property

∠UVW=∠WXU as given

hence, UW=UW and ∠UVW=∠WXU by reflexive property and given in diagram.

The correct option is d)
