Answer:
B. 48Step-by-step explanation:
Use the ratio of corresponding sides of similar triangles
x/64 = (100 - 64)/xx/64 = 36/xx² = 64*36x² = 8²*6²x = 8*6x = 48Correct choice is B
Rest Hypotenuse part of triangle=100-64=36
Now

Step-by-step explanation:
The length of a rectangular frame is represented by the expression 2x 4, and the width of the rectangular frame is represented by the expression 2x 10. write an equation to solve for the width of a rectangular frame that has a total area of 120 square inches. 2x2 20x − 80 = 0 4x2 28x 40 = 0 4x2 28x − 80 = 0 x2 8x 20 = 0
The equation that can be ued to solve for the width of the rectangular frame is 2x² + 14x - 40 = 0.
What is the equation that can be used to solve for the width?A rectangle is a 2-dimensional quadrilateral with four right angles.
Area of a rectangle = length x width
(2x + 4) x (2x + 10) = 120
Expand the brackets
4x² + 20x + 8x + 40 = 120
Add similar terms
4x² +28x + 40 = 120
4x² +28x - 80 = 0
Divide through by 2
2x² + 14x - 40 = 0

Find the midpoint of the line segment with end coordinates of:
(-2,-4) and (-1,-5)
[tex]\qquad\qquad\huge\underline{{\sf Answer}}♨[/tex]
Let's use section formula ~

Zachary is an engineer and studies trains. He found this interesting problem involving a passenger train and a freight train:
A passenger train left New York and traveled North while a freight left from the same place, at the same time and traveled South. After traveling for 6 hours the trains were 720 miles apart. If the passenger train was traveling at 80 mph, how fast was the freight train traveling
Answer:
40 m/hr
Step-by-step explanation:
6 hours * 80 m/hr + 6 hours * x m/hr = 720 miles
6 * 80 + 6 * x = 720
x = 40 m/hr

Consider parallelogram VWXY below.
Use the information given in the figure to find m∠YXV, m∠Y, and x.
Answer:
56°, 84°, 3 unitsStep-by-step explanation:
Properties of a parallelogram
Two adjacent angles are supplementaryOpposite angles are congruentOpposite sides are parallel and congruentUse the properties to find the required parameters
1) Find m∠YXV
m∠YXV + m∠VXW + m∠VWX = 180°m∠YXV + 40° + 84° = 180°m∠YXV = 180° - 124°m∠YXV = 56°2) Find m∠Y
m∠Y = m∠W = 84°3) Find x
2x = 6x = 6/2x = 3Answer:
m∠YXV = 56°
m∠Y = 84°
x = 3
Step-by-step explanation:
Sum of interior angles of a triangle = 180°
⇒ m∠W + m∠WVX + m∠VXW = 180°
⇒ 84° + m∠WVX + 40° = 180°
⇒ m∠WVX = 56°
As VW ║ YX and YV ║ XW then m∠WVX = m∠YXV
So m∠YXV = 56°
In a parallelogram, opposite angles are congruent
⇒ m∠Y = m∠W
⇒ m∠Y = 84°
In a parallelogram, opposite sides lengths are congruent
⇒ VW = YX
⇒ 2x = 6
⇒ x = 6 ÷ 2
⇒ x = 3

= 42.5
u= V42.5
= V170 /2
≈6.52
Answer:
6.519 cm
Step-by-step explanation:
Mmkay, so, you have to use the Pythagorean Theorem to find the actual length, which is a^2 + b^2 = c^2
a = 4.9 cm
b = 4.3 cm
4.9^2 is 24.01
4.3^2 is 18.49
Now add the two together:
24.01 + 18.49 = 42.5
Finally, we need to find the square root of 42.5
sqrt(42.5) = 6.519 cm
(rounding to nearest thousandth cuz it said so right by the answer box lol)

x^2-6x+1=0 solve by completing square
Answer:
x = 3 ± 2[tex]\sqrt{2}[/tex]
Step-by-step explanation:
x² - 6x + 1 = 0 ( subtract 1 from both sides )
x² - 6x = - 1
to complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 3)x + 9 = - 1 + 9
(x - 3)² = 8 ( take square root of both sides )
x - 3 = ± [tex]\sqrt{8}[/tex] = ± 2[tex]\sqrt{2}[/tex] ( add 3 to both sides )
x = 3 ± 2[tex]\sqrt{2}[/tex]
What is the solution for 2.5x-5=5?
Answer:
Simplifying
2.5x + -5 = 5
Reorder the terms:
-5 + 2.5x = 5
Solving
-5 + 2.5x = 5
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '5' to each side of the equation.
-5 + 5 + 2.5x = 5 + 5
Combine like terms: -5 + 5 = 0
0 + 2.5x = 5 + 5
2.5x = 5 + 5
Combine like terms: 5 + 5 = 10
2.5x = 10
Divide each side by '2.5'.
x = 4
Simplifying
x = 4

What is the square root of -2i?
Answer:
1-i and -1+i
Step-by-step explanation:
We are to find the square roots of [tex]z=0-2i[/tex]. First, convert from Cartesian to polar form:
[tex]r=\sqrt{a^2+b^2}\\r=\sqrt{0^2+(-2)^2}\\r=\sqrt{0+4}\\r=\sqrt{4}\\r=2[/tex]
[tex]\theta=tan^{-1}(\frac{b}{a})\\ \theta=tan^{-1}(\frac{-2}{0})\\\theta=\frac{3\pi}{2}[/tex]
[tex]z=2(\cos\frac{3\pi}{2}+i\sin\frac{3\pi}{2})[/tex]
Next, use the formula [tex]\displaystyle \sqrt[n]{r}\biggr[\cis\biggr(\frac{\theta+2\pi k}{n}\biggr)\biggr][/tex] where [tex]\displaystyle k=0,1,2,...\:,n-1[/tex] to find the square roots:
When k=1
[tex]\displaystyle \sqrt[2]{2}\biggr[cis\biggr(\frac{\frac{3\pi}{2}+2\pi(1)}{2}\biggr)\biggr][/tex]
[tex]\displaystyle \sqrt{2}\biggr[cis\biggr(\frac{3\pi}{4}+\pi\biggr)\biggr][/tex]
[tex]\sqrt{2}\biggr(cis\frac{7\pi}{4}\biggr)[/tex]
[tex]\sqrt{2}(\cos\frac{7\pi}{4}+i\sin\frac{7\pi}{4})\\ \\\sqrt{2}(\frac{\sqrt{2}}{2}-\frac{\sqrt{2}}{2}i)\\ \\1-i[/tex]
When k=0
[tex]\displaystyle \sqrt[2]{2}\biggr[cis\biggr(\frac{\frac{3\pi}{2}+2\pi(0)}{2}\biggr)\biggr][/tex]
[tex]\sqrt{2}\biggr(cis\frac{3\pi}{4}\biggr)[/tex]
[tex]\sqrt{2}(\cos\frac{3\pi}{4}+i\sin\frac{3\pi}{4})\\ \\\sqrt{2}(-\frac{\sqrt{2}}{2}+\frac{\sqrt{2}}{2}i)\\ \\-1+i[/tex]
Thus, the square roots of -2i are 1-i and -1+i
