Given the equation square root of quantity 3x plus 4 end quantity equals 5, solve for x and identify if it is an extraneous solution.

7; solution is not extraneous

7; solution is extraneous

four thirds; solution is not extraneous

four thirds; solution is extraneous

7; solution is not extraneous

Step-by-step explanation:

we have

Solve for x

squared both sides

subtract 4 both sides

Divide by 3 both sides

Verify

Substitute the value of x in the original equation

----> is true

therefore

The value of x=7 is a solution, Is not a extraneous

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
