The area of the planned school garden have dimensions of g + 4 and g + 10 respectively.
What is an equation?An equation is an expression that shows the relationship between two or more variables and numbers.
Given the area of the planned school garden as:
A = g² + 14g + 40
A = g² + 10g + 4g + 40 = g(g + 10) + 4(g + 10)
A = (g + 4)(g + 10)

A washer and a dryer cost $819 combined. The washer costs $69 more than the dryer. What is the cost of the dryer?
a
si
х
?
Answer:
the dryer costs $450
step-by-step explanation:
w + d = 831
w = d-69 (they told us we will have to take $69 from the cost of the dryer to determine the cost of the washer)
(d-69) + d = 831
Let's combine like terms
2d - 69 = 831
add 69 to both sides to solve for d
2d = 900
divide both sides by 2 to solve for d
d = 450; the dryer costs $450

A candle burns down at the rate of 0.5 inches per hour. The original height of the candle was 8 inches.
Part A: Write a list of 6 ordered pairs to show the height of the candle in inches (y) as a function of time in hours (x) from the first hour after it started burning. For example, the point (0, 8) would represent a height of 8 inches after 0 hours. Explain how you obtained the ordered pairs. (5 points)
Part B: Is this relation a function? Justify your answer using the list of ordered pairs you created in Part A. (2 points)
Part C: If the rate at which the candle burned was 0.4 inches per hour instead of 0.5 inches per hour, would the relation be a function? Explain your answer using input and output values. (3 points)
The linear equations of the candles are y = 0.5x + 8 and y = 0.4x + 8. And both relationships are the function.
What is the linear system?A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
A candle burns down at the rate of 0.5 inches per hour.
The original height of the candle was 8 inches.
Let y be the height of the candle and x be the number of hours.
Then the linear equation will be given as
[tex]\rm y = mx + c[/tex]
where m is the rate and c is the initial value. Then the linear equation of the candle will be
y = -0.5 x + 8
The function is a linear function.
If the value of m is replaced by 0.4. Then the linear equation will be
y = 0.4x + 8
And this will also be a linear function.

A hotel builds an isosceles trapezoidal pool for children. it orders a tarp to cover the pool when not in use. what is the area of the tarp?
to find the height. first find that d is 60,45,or 120. this means the height of the trapezoid is approximately 2.5,4.3,or 3.5 feet. so the area of the tarp is approximately 47.3,30.0 or 38.5 square feet.
The area of the trapezoidal tarp in the hotel is 47.3 square inches
How to determine the area of the tarp?The area of a trapezoid is calculated using:
Area = 0.5 * (Sum of parallel sides) * Height
From the complete question, the parallel sides are:
10 ft and 12 ft
So, we have:
Area = 0.5 * (10 + 12) * h
Evaluate
Area = 11 * h
The height (h) is calculated using the following cosine function
cos(120 - 90) = h/5
This gives
cos(30) = h/5
Make h the subject
h = 5cos(30)
Evaluate
h = 4.3
So, we have:
Area = 11 * 4.3
Evaluate
Area = 47.3
Hence, the area of the trapezoid is 47.3 square inches

The length of a rectangle is 5times
the breadth, if the perimeter of a
rectangle is 72cm find the area.
Answer:
Step-by-step explanation:
Formula Development
Let the width = w
Let the Length = 5*w
P = 72
P =2w + 2L
Area = 5w * w
Solution
Start with the Perimeter. Solve for w.
P = 2w + 2L Substitute the givens
72 = 2w + 2*5w Combine
72 = 2w + 10w Combine Combine again
72 = 12 w Divide by 12
72/12 = 12w/12
w = 6
Now for the area
Area = 5w * w
w = 6
Area = 5*6*6

Find the minimum distance between the point (-5,1) and the line x = -2
Answer:
3
Step-by-step explanation:
The minimum distance would be when there would be a horizontal line connecting the point (-5,1) with the line x=-2. So there would be a line from (-5,1) to (-2,1) which would be a straight line of 3 since -2 +5 = 3.

ABCD is a rhombus.
y
The coordinates of A are (5, 11)
The equation of the diagonal DB is y = x + 5
The equation of the diagonal AC can be written
in the form y = mx + c where m and c are integers.
Work out the value of m and the value of c.
From the information given, it is correct to state that M = - 3; while c = 26. This problem relates to a Rhombus. See the definition of a Rhombus below.
What is a Rhombus?A Rhombus is a 2-dimensional quadrilateral whose sides have equal length.
What are the steps for finding M and C?It is given that ABCD is a Rhombus. This means that
AC ⊥ BD; andLine DB is y = (1/3)x + 5Hence, the slope of AC = -3.
This is arrived at as follows:
Given that the diagonals of Rhombus' are perpendicular, hence
I/3 x m = -1 ⇒ -3
⇒ Line y-11 = -3 (x-5)
⇒ Line AC thus ⇒ y = -3x + 26
Recall that the coordinates are (5, 11). Thus let y = -3x + b
Hence, -3 x 5 + b = 11
b = 11 + 15
b = 26.
Therefore the equation is given as:
y = -3X + 26 were:
m = -3; and
c = 26

An equation of a circle is x^2 - 8x + 16 +y^2 + 10y + 25 = 81
What is the radius of the circle?
What is the center of the circle?
Answer:
the radius: r = 9the center: (4, -5)Step-by-step explanation:
The equation of a circle:
(x - a)² + (y - b)² = r²(a, b) - the center of a circle
r - the radius of a circle
x² - 8x + 16 + y² + 10y + 25 = 81
(x² - 2(x)(4) + 4²) + (y² + 2(y)(5) + 5²) = 81
use: (a - b)² = a² - 2ab + b² and (a + b)² = a² - 2ab + b²
(x - 4)² + (y + 5)² = 9²
Therefore
the radius: r = 9
the center: (4, -5)
The radius is 9 and the center of the circle (4, -5)
What is the center of a circle?A circle's center is a point throughout the circle that is equally spaced from every other point on the circumference. The line of refraction symmetry is formed by all lines that traverse the circle. Additionally, every angle possesses rotational symmetry surrounding the centre.
The equation of a circle:
(x - a)² + (y - b)² = r²
The center of a circle will be (a, b)
The radius of a circle will be r
x² - 8x + 16 + y² + 10y + 25 = 81
Solving the above equation on the basis of the Equation of a circle.
(x² - 2(x)(4) + 4²) + (y² + 2(y)(5) + 5²) = 81
Using the identity in the above-given equation.
(a - b)² = a² - 2ab + b² and (a + b)² = a² - 2ab + b²
(x - 4)² + (y + 5)² = 9²
The center of the circle will be at coordinates 4 and 5. And the radius of the circle derived is 9.
