<span>Simplifying g2 = 13 + -12g Solving g2 = 13 + -12g Solving for variable 'g'. Reorder the terms: -13 + 12g + g2 = 13 + -12g + -13 + 12g Reorder the terms: -13 + 12g + g2 = 13 + -13 + -12g + 12g Combine like terms: 13 + -13 = 0 -13 + 12g + g2 = 0 + -12g + 12g -13 + 12g + g2 = -12g + 12g Combine like terms: -12g + 12g = 0 -13 + 12g + g2 = 0 Factor a trinomial. (-13 + -1g)(1 + -1g) = 0 Subproblem 1Set the factor '(-13 + -1g)' equal to zero and attempt to solve: Simplifying -13 + -1g = 0 Solving -13 + -1g = 0 Move all terms containing g to the left, all other terms to the right. Add '13' to each side of the equation. -13 + 13 + -1g = 0 + 13 Combine like terms: -13 + 13 = 0 0 + -1g = 0 + 13 -1g = 0 + 13 Combine like terms: 0 + 13 = 13 -1g = 13 Divide each side by '-1'. g = -13 Simplifying g = -13 Subproblem 2Set the factor '(1 + -1g)' equal to zero and attempt to solve: Simplifying 1 + -1g = 0 Solving 1 + -1g = 0 Move all terms containing g to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + -1g = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -1g = 0 + -1 -1g = 0 + -1 Combine like terms: 0 + -1 = -1 -1g = -1 Divide each side by '-1'. g = 1 Simplifying g = 1Solutiong = {-13, 1}

1. What is the extraneous solution of √x−3 + x = 9?
Sunny_sXe [5.5K]

Answer:

1. x = 12

2. 3∛4 feet.

Step-by-step explanation:

1. We are given the equation of x as \sqrt{x - 3} + x = 9 and we have to find the extraneous solution of the equation.

Now, \sqrt{x - 3} + x = 9 ............. (1)

⇒ \sqrt{x - 3} = 9 - x

Squaring both sides we get,

⇒ x - 3 = 81 - 18x + x²

⇒ x² - 19x + 84 = 0

⇒ x² - 12x - 7x + 84 = 0

⇒ (x - 12)(x - 7) = 0

⇒ x = 12 or 7.

Now, putting x = 12 in the equation (1) we get,

\sqrt{12 - 3} + 12 \neq   9

Again, putting x = 7 in the equation (1) we get,

\sqrt{7 - 3} + 7 = 9

Therefore, x = 12 is an extraneous solution of this equation. (Answer)

2. The volume of a cube with side lengths a ft. is given to be 108 ft³.

So, a³ = 108

⇒ a = 3∛4 feet.

Therefore, the length of the sides of the cube are each 3∛4 feet. (Answer)
