A. 24 m x 26 m
B. 25 m x 25 m
C. 50 m x 50 m
D. 50 m x 25 m
Answer:
Step-by-step explanation:
4) B , C and D represents the quadratic equation.
B) width = w
length = l = 2w + 2
Area = 24 square m
l *w = 24
(2w + 2)*w = 24
2w*w + 2w = 24
2w² + 2w - 24 = 0
Divide the entire equation by 2
w² + w - 12 = 0
C) width = w
Length = w + 3
Area = 40 m²
(w + 3 ) *w = 56
w*w + 3*w = 56
w² + 3w - 56 = 0
D) Width = w
Length = w + 8
Area = 40
(w + 8)*w = 40
w² - 8w - 40 = 0
5) B) 25 * 25
25 *25 gives the largest area that has its perimeter 100

Solve for x
Answer:
x = 11°
Step-by-step explanation:
Because of Alternate Exterior Angles, 5x - 12 = 43. Now, let's solve.
=> 5x - 12 = 43
=> 5x = 55
=> x = 11°
Hoped this helped.
Answer:
x = 11
Step-by-step explanation:
Alternate exterior angles are congruent where a transversal crosses parallel lines. That means ...
(5x -12)° = 43°
5x = 55 . . . . . . . divide by °, add 12
x = 11 . . . . . . . . . divide by 5

The measure of the second angle of a triangle is twice the measure of the first. The measure of the third angle is six times the measure of the first. Find the measure of the third angle
Answer:
120°
Step-by-step explanation:
The sum of all angle measurements for the interior of the angle is 180°.
Let the first angle measurement be denoted as "x".
The second angle measurement is twice that of the first, or "2x".
The third angle measurement is six times of that of the first, or "6x".
Set the equation:
x + 2x + 6x = 180
Simplify. Combine like terms. Like terms are terms with the same, as well as same amount of said variable:
(x + 2x + 6x) = 180
(9x) = 180
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Divide 9 from both sides of the equation:
(9x)/9 = (180)/9
x = 180/9 = 20
x = 20
Next, plug in 20 for x for the third measurement:
6x = 6 * (20) = 120°
120° is your answer.

A game lasts 5/8 hours. Jane played 4 of these games.
For how long did she play in total?
Answer: 2 hours 30 minutes in total.
Step-by-step explanation: Because when it says that a game lasts for 5/8 hours and Jane only play 4 of these games, Which means that you have to multiply the number of hours lasted by the total number of games that have been played. Therfore 5/8 x 4 = 20/8 but you simplify your answer and you will get 2 hours and 30 minutes in total.

What are the slope and y-intercept of the line?
Question 1 options:
Slope = -2, y-Intercept = -4
Slope = 1, y-Intercept = 2
Slope = -1, y-Intercept = 2
Slope = 2, y-Intercept = -4
The slope of the line is 1 and the y intercept is 2.
The linear equation is given by:
y = mx + b;
where y, x are variables, m is the slope of the line and b is the y intercept
Let n represent the number of inches a plant grows after m months.
Taking two points (0, 2) and (6, 8), the equation is given by:
[tex]n-n_1=\frac{n_2-n_1}{m_2-m_!} (m-m_1)\\\\n-2=\frac{8-2}{6-0}(m-0) \\\\n=m+2[/tex]
Therefore the slope of the line is 1 and the y intercept is 2.

Find the values of x and y that make the quadrilateral a parallelogram. (4x + 13) (4y + 7)º (3x - 8) (5x - 12)
The sum of angles in a parallelogram adds up to 360 degrees
The values of x and y are 25 and 15, respectively.
The angles are given as:
[tex]\mathbf{\angle 1 = 4x + 13}[/tex]
[tex]\mathbf{\angle 2 = 4y + 7}[/tex]
[tex]\mathbf{\angle 3 = 3x - 8}[/tex]
[tex]\mathbf{\angle 4= 5x - 12}[/tex]
The opposite angles of a parallelogram are equal.
So, we have:
[tex]\mathbf{4x + 13 = 5x - 12}[/tex]
Collect like terms
[tex]\mathbf{5x - 4x = 13 + 12}[/tex]
[tex]\mathbf{x = 25}[/tex]
Simiarly, we have:
[tex]\mathbf{4y + 7 = 3x -8}[/tex]
Substitute 25 for x
[tex]\mathbf{4y + 7 = 3 \times 25 -8}[/tex]
[tex]\mathbf{4y + 7 = 75 -8}[/tex]
[tex]\mathbf{4y + 7 = 67}[/tex]
Subtract 7 to both sides
[tex]\mathbf{4y = 60}[/tex]
Divide both sides by 4
[tex]\mathbf{y = 15}[/tex]
Hence, the values of x and y are 25 and 15, respectively.

the angles of a triangle are in the ratio of 7:6:2. find the measure of each angle.
A. 84, 72, 24.
B. 56, 48, 16.
C. 90, 80, 10,
D. 42, 36, 12
Answer:
A. 84, 72, 24
Step-by-step explanation:
Let the angles be - 7x 6x and 2x
7x + 6x + 2x = 180° (angle sum property)
15x = 180°
x = 180° ÷ 15 = 12
Therefore, the angles are : 7x = 7 × 12 = 84
6x = 6 × 12 = 72
2x = 2 × 12 = 24

Answer:

Step-by-step explanation:
Find common denominator
[tex]\frac{d}{3} +\frac{3*9.9}{12.9}[/tex]
Combine fractions with common denominator
[tex]\frac{d+3*9.9}{3} =12.9[/tex]
Multiply the numbers
[tex]\frac{d+29.7}{3} =12.9[/tex]
Multiply all terms by the same value to eliminate fraction denominators
[tex]3(\frac{x+29.7}{3} )=3 * 12.9[/tex]
Cancel multiplied terms that are in the denominator
x=29.7= 3 · 12.9
Multiply the number
x= 12.9=38.9
Subtract 297 from both sides of the equation
x+29.7-29.7=38.9-29.7
Simplify
x = 9.0
Hence, the answer is 9.
