The geometric mean of x+3 and 4x+1 is 2x+1. Find all possible values of x.

Anastaziya [24]

Answer:

$x = - \frac{2}{9}$

Step-by-step explanation:

Since, the geometric mean of x+3 and 4x+1 is 2x+1.

Therefore, by geometric mean theorem:

${(2x + 1)}^{2} = (x + 3)(4x + 1) \\ \\ \cancel{4 {x}^{2}} + 4x + 1 = \cancel{4 {x}^{2}} + x + 12x + 3 \\ \\ 4x + 1 = 13x + 3 \\ \\ 4x - 13x = 3 - 1 \\ \\ - 9x = 2 \\ \\ x = - \frac{2}{9}$

The distance between points (3, 7) and (x₁, y ) is the square root of (x₁ - 3)² + (y₁ - 7)².

nasty-shy [4]

Based on the distance formula, the distance between points (3, 7) and (x1, y) is: $\sqrt{(x_1 - 3)^2 + (y_1 - 7)^2}$ . SO, it is TRUE.

<h3>What is the Distance Formula?</h3>

The distance formula which can be applied to find the distance between two coordinate points is: $d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}$ .

Given the points:

(x1, y1)

(3, 7) = (x2, y2)

Substitute

$d = \sqrt{(x_1 - 3)^2 + (y_1 - 7)^2}$

Therefore, the statement that says the distance between points (3, 7) and (x1, y) = $\sqrt{(x_1 - 3)^2 + (y_1 - 7)^2}$ , is TRUE.
