Answer:

Step-by-step explanation:

log(2x + 6) +8 = 3

Solve this log equation for x

First subtract 8 from both sides

log(2x+6)= -5

Now we convert it into exponential form

If log(x) = a then 10^a = x

log(2x+6)= -5 becomes

subtract 6 from both sides

Now we divide by 2 on both sides

x= -3 approximately

Now that you have x² - 8x 16 = 9 16, apply the square root property to the equation.

vitfil [10]

The square root property to the equation will be (x – 4)² = 25. And the solutions will be the negative 1 and 9.

<h3>What is a quadratic equation?</h3>

The quadratic equation is given as ax² + bx + c = 0. Then the degree of the equation will be 2. Then we have

The equation is given below.

x² – 8x + 16 = 9 + 16

Then the equation can be written as

(x – 4)² = 25

x – 4 = ±5

x = 4 ± 5

x = -1, 9

The segment that extends from the vertex of a triangle to the _____ side and is perpendicular to the side of the triangle is cal

arsen [322]

Answer:

The segment that extends from the vertex of a triangle to the <u>opposite</u> side and is perpendicular to the side of the triangle is called the altitude.

Step-by-step explanation:

Please find the attachment.

We have been given an incomplete statement. We are supposed to complete the given statement.

Statement: The segment that extends from the vertex of a triangle to the _____ side and is perpendicular to the side of the triangle is called the altitude.

By the definition of altitude, an altitude of a triangle is a line segment from a vertex that is perpendicular to the opposite side.

Therefore, the correct word for our given statement would be "opposite".
