Answer:

The answer is C.

Step-by-step explanation:

The L-shape can be divided into a rectangle of 20ft by 12-5=7ft and a square of 5ft by 5ft

So its area is the sum of the rectangle and the square

= 20*7 + 5*5

= 140 +25

= 165 ft^2

The answer is C.

Answer:

165 ft^2

Step-by-step explanation:

We need to break the figure into 2 parts

We have the square at the bottom right

The square is 5 by 5

A = 5*5 = 25

The rectangle is then 20 by (12-5) =7

The area of the rectangle is

A = 20 *7 = 140

Add the areas together

140+ 25

165 ft^2

If there are 40 boys and 60 girls in a room, fill out all of the possible ratios of boys to girls that could be made.

galina1969 [7]

40+60=100. So one person equals 1%, meaning 40% are boys and 60% are girls. By simplifying, we will find that possible ratios below the value of 100 are 40:60, 4:6, 2:3, and 20:30.

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

Mariana [72]

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:

$9x\² - 36x + 36 = 0$

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

$ax\² + bx + c = 0$

The discriminant (d) is calculated as:

$d = b\² - 4ac$

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:

$x\² - x + 4 = 0$

The above equation can be represented as:

$ax\² + bx + c = 0$

The discriminant (d) is calculated as:

$d = b\² - 4ac$

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:

$4x\² + 23 - 35$

Evaluate the difference

$4x\² -12$

Factor out 4

$4(x\² -3)$

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