5 0

\text {Hello! Your answer would be}

\fbox { 3.5 and -3.5}

\text {Since we are finding the absolute value of 3.5 we find the opposite of 3.5}

\text {Note: Finding an absolute value of a positive number will always equal a positive.}

\text {-3.5 will equal to 3.5 since it's the opposite of 3.5}

\text {You are also finding the opposite of 3.5}

\text {3.5 will also equal to 3.5 because it's already a positive number so your not doing the opposite.}

\text {Best of Luck!}

\text {-LimitedX}

What is the length? In algebra DUE TOMORROW
Mamont248 [21]
The formula for volume is V=lhw, or length times height times weight. To find the length, you divide the volume by the height and width. 

In this case, divide 3,060 first by 12, the height, then by 15, the width.

3,060/12=255
255/15=17

The length is 17.

Part A: Describe the solution(s) to 9x² - 36x + 36 = 0 by just determining the radicand. Show your work. (10 points) Part B: Des
Alik [6]

The solution to the equations are:

  • 9x² - 36x + 36 = 0 has two equal real solutions
  • x² - x + 4 = 0 has no real solutions
  • The factored expression of 4x² + 23 – 35 is 4(x² -3)

<h3>Part A: Describe the solution</h3>

The equation is given as:

9x² - 36x + 36 = 0

The above equation is a quadratic equation which can be represented as:

ax² + bx + c = 0

The discriminant (d) is calculated as:

d = b² - 4ac

So, we have:

d = (-36)² - 4 * 9 * 36

d = 0

A discriminant of 0 means that the equation has two equal real solutions

Hence, 9x² - 36x + 36 = 0 has two equal real solutions

<h3>Part B: Describe the solution</h3>

The equation is given as:

x² - x + 4 = 0

The above equation can be represented as:

ax² + bx + c = 0

The discriminant (d) is calculated as:

d = b² - 4ac

So, we have:

d = (-1)² - 4 * 1 * 4

d = -15

A discriminant of -15 means that the equation has no real solutions

Hence, x² - x + 4 = 0 has no real solutions

<h3>Part C: The solution to the expression</h3>

We have:

4x² + 23 – 35

Evaluate the difference

4x² -12

Factor out 4

4(x² -3)

Hence, the factored expression of 4x² + 23 – 35 is 4(x² -3)
