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.

Solve for p. −4.5 + p6= −18.9
Vesna [10]

Answer:

-2.4

Step-by-step explanation:

Given data

We have the expression before us as

−4.5 + p6= −18.9

Collect like terms

p6= −18.9+4.5

p6= -14.4

Divide both sides by 6

p= -14.4/6

p=-2.4

Hence the value of p= -2.4

Evaluate5− t/3 when t=12 ​
Novosadov [1.4K]

Answer:

1

Step-by-step explanation:

5 -  \frac{t}{3} =  \frac{5}{1} - \frac{12}{3} = 5 - 4 = 1

or

5 -  \frac{t}{3} =  \frac{5}{1} -  \frac{12}{3} =  \frac{15 - 12}{3} =  \frac{3}{3} = 1

Hope this helps ;) ❤❤❤
