Answer:
Step-by-step explanation:
The question is ambiguous. Is the longer side the hypotenuse of the length of the other leg making up the right angle.
The missing side is the hypotenuse
x + 2x + sqrt(x^2 + (2x)^2 ) = 28
3x + sqrt(x^2 + (2x)^2 ) = 28
sqrt(x^2 + (2x)^2 ) = 28 - 3x Square both sides
x^2 + 4x^2 = 784 - 168x + 9x^2
5x^2 = 784 - 168x + 9x^2
0 = 784 - 168x + 4x^2 Use the quadratic formula to solve this. It does not factor.
x = 5.34
2x = 10.68
hypotenuse = sqrt (5*5.35^2)
hypotenuse = 5.35*sqrt(5)
hypotenuse = 11.96
=============
Shortest leg = 5.35
Other leg = 10.7
Hypotenuse = 11.96
Total = 28.01
So the answer is mathematically correct for the hypotenuse being the unknown.
#################################
If the leg is unknown, then I'll set up the equation and you can solve it.
x + sqrt(4x^2 - x^2) + 2x = 28 subtract x from both sides
sqrt(4x^2 - x^2) + 3x = 28 Square both sides
sqrt(3x^2) = 28 - 3x
3x^2 = 784 - 168 + 9x^2
6x^2 - 168x + 784 = 0
x = 5.91
You can carry on from here.
Answer:
Step-by-step explanation:
Let's call the sides a,b,c
P=28 so
a+b+c=28
twice as long means a = 2b substitute in equation above
2b+b+c=28
3b+c=28
but we also know is a right triangle so thhe Pythagorean Theorem can be apply yet we shoud figure what side is the hypothenuse
Since a=2b, b-cannot be the hypothenuse because is not the biger side so is eithher a or c
a² = b²+c² or c² = b²+a² substitute a² for (2b)²=4b²
4b² = b²+c² or c² = b²+ 4b²
3b² = c² or c² = 5b²
yet 3b+c=28, c=28-3b, so c²= 28²- 168b+9b² =9b²-168b+784
9b²-168b+784=3b² or 9b²-168b+784=5b²
6b²-168b+784=0 or 4b²-168b+784=0
and probably solve using quadratic equations

As soon as a new car is purchased and driven away from the dealership, it begins to lose its value, or depreciate. Alonso bought a 1994 Plymouth Neon for $9559. One year later, the value of the car was $8500. What was the percent of decrease of the value of the car?
P.S. This is a percent increase/decrrease
from: 9559
to: 8500
%/100 = differences of to and from/ from ( before the number )
( no negative difference, bigger number subtract smaller number)
Answer:
11%
Step-by-step explanation:
$9559-$8500=1059
1059/9559= .110786
.110786 x 100= 11.0786%
11.0786%= 11%

Find the equation that passes through points A and B
Answer:
Step-by-step explanation:
A(1,7); B(-3,-1); slope m =(-1-7)/-3-1) = -8/-4 = 2
Equation of a line AB is
((y-y1) = m(x-x1)
y - 7 = 2(x-1)
y - 7 = 2x-2
y = 2x + 5
Answer:
y = 2x +5
Step-by-step explanation:
Equation of a line
The point-slope form of the equation of a line is:
y - k = m ( x - h )
Where m is the slope and (h,k) is a point through which the line passes.
Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
The image provides two points A(1,7) and B(-3,-1), thus the slope is:
[tex]\displaystyle m=\frac{-1-7}{-3-1}[/tex]
[tex]\displaystyle m=\frac{-8}{-4}[/tex]
m = 2
Now we apply the point-slope form taking the point (1,7):
y - 7 = 2 ( x - 1 )
Operating:
y - 7 = 2x - 2
Adding 7:
y = 2x +5

What is the domain and range please?
9514 1404 393
Answer:
domain: {3, 5, 7, 11, 13, 15}
range: {-18, -2, 0, 8, 14}
yes, it is a function
Step-by-step explanation:
The domain is the list of numbers in the x column: {3, 5, 7, 11, 13, 15}.
The range is the list of numbers in the y column. Usually duplicates are removed. It is often useful to order the numbers, but is not strictly necessary. The range is {-18, -2, 0, 8, 14}.
No x-value is repeated, so the relation IS A FUNCTION.
how do i find the slope of a line graph
Answer:
rise over run
Step-by-step explanation:
you count the y axis from one point on a line to another then you count the x axis from the same two points and turn this into a fraction of y over x
y/x this is the slope

Find the area of the shape below.
16 cm
7 cm
7 cm
20 cm
Answer:
Area = 230 cm
Step-by-step explanation:
We can split this shape into different parts: a rectangle and a triangle (I attached an image below as a visual aid).
The area of a rectangle is given as:
[tex]Area = width * length[/tex]
and the area of a triangle is given as:
[tex]Area = \frac{1}{2} *base * height[/tex]
Let's first solve for the area of the rectangle. The width of the rectangle is 20cm, and the height of the rectangle is 7cm. So, the area is 7 × 20 = 140cm.
Now, let's solve for the area of the triangle. The base of the triangle is 20 cm, and the height of the rectangle is 16 - 7 = 9cm. So, the area is [tex]\frac{1}{2} * 20 * 9[/tex] = 90cm.
We add the two values together to get the combined area of the shape. 140 + 90 = 230 cm.

The line BD will be 10.5cm in the triangle ABC. Thus option D is correct.
What is a triangle?A closed shape with both inner and exterior angles, a triangular is created by three lines. the fundamental geometric shapes. a vertex-filled triangle. There is only one distinct triangle if the product of two fades on the sides is bigger than the longest side.
The value of AE is given as 21.
From the diagram that is given, it is indicated that according to the midpoint theorem
BD║AE
Also, BD= 1/2 ×AE
BD = 21/2
BD = 10.5 cm.
Therefore, option D is the correct option.
