A. -3

B. -1/3

C. 1/3

D. 3

Answer:

C is the correct option

Step-by-step explanation:

hope this helps.

By, Cross multiplying, we get

[tex]⇢2x(x - 1) = (2x - 1)(x + 2)[/tex]

[tex]⇢2 {x}^{2} - 2x = 2x(x + 2) - 1( x+ 2)[/tex]

[tex]⇢2 {x}^{2} - 2x = 2 {x}^{2} + 4x - x - 2[/tex]

Here, [tex]2 {x}^{2} [/tex] from both sides will get cancelled

[tex] ⇢- 2x = 3x - 2[/tex]

[tex]⇢ - 2x - 3x = - 2[/tex]

[tex] ⇢- 5x = - 2[/tex]

[tex] ⇢x = \frac{ - 2}{ - 5} [/tex]

[tex] ⇢ \underline { \boxed{ x = \frac{2}{5} }} [/tex]

Answer:

[tex]x=\frac{2}{5}[/tex]

Step-by-step explanation:

[tex]\frac{2 x}{x+2}-\frac{x}{x-1}=1[/tex]

[tex]\begin{aligned} & \Leftrightarrow \frac{2 x(x-1)}{(x+2)(x-1)}-\frac{x(x+2)}{(x-1)(x+2)}=1 \\& \Leftrightarrow \frac{2 x^{2}-2 x}{(x+2)(x-1)}-\frac{\left(x^{2}+2 x\right)}{(x+2)(x-1)}=1 \\& \Leftrightarrow \frac{2 x^{2}-2 x-\left(x^{2}+2 x\right)}{(x+2)(x-1)}=1 \\& \Leftrightarrow \frac{2 x^{2}-2 x-x^{2}-2 x}{(x+2)(x-1)}=1 \\& \Leftrightarrow \frac{x^{2}-4 x}{(x+2)(x-1)}=1 \\\end{aligned}[/tex]

[tex]\begin{aligned}& \Leftrightarrow x^{2}-4 x=(x+2)(x-1) \\& \Leftrightarrow x^{2}-4 x=x^{2}-x+2 x-2 \\& \Leftrightarrow x^{2}-4 x=x^{2}+x-2 \\& \Leftrightarrow-4 x=x-2 \\& \Leftrightarrow 5 x=2\end{aligned}[/tex]

therefore,

[tex]x=\frac{2}{5}[/tex]

Solving

Answer:

The best name for the shape of his kite is a rectangular rhombus.

Step-by-step explanation:

Answer:

m∠CAB = 90°

BD = 9

m∠ABC = 90°

arc AEC = 180°

AD = 14.5

Step-by-step explanation:

Question 1

The angle between the radius and a tangent to the circle is always 90°.

Therefore, as AC is the radius and AB is a tangent segment, m∠CAB=90°

As m∠CAB = 90°, we can use Pythagoras' Theorem to find BC (hypotenuse):

   AC² + AB² = BC²

⇒ 8² + 15² = BC²

⇒ BC² = 289

⇒ BC = 17

As CD is the radius, CD = 8

Therefore, BD = BC - CD = 17 - 8 = 9

Question 2

If D is the center, then AC is the diameter. Angles at the circumference in a semicircle are always 90°.  Therefore, m∠ABC = 90°

As AC is the diameter, arc AEC is half of the circle.  

Therefore, arc AEC = 360° ÷ 2 = 180°

As m∠ABC = 90°, we can use Pythagoras' Theorem to find AC (hypotenuse):

   BC² + AB² = AC²

⇒ 20² + 21² = AC²

⇒ AC² = 841

⇒ AC = 29

AD is the radius.  A radius is half the diameter.

Therefore, AD = AC ÷ 2 = 29 ÷ 2 = 14.5

Answer:

888 centimeters^2

Step-by-step explanation:

SA: 2×(22×10 + 22×7 + 10×7) = 888 centimeters^2 (to the power of 2)

Answer:

The answer is : 11°

Step-by-step explanation:

MKL+KLM = LMN

= (3x+19)°+(2x+8)° = (7x+5)°

= 5+27° = 7x+5°

= 2x = 22°

= x = 11°

Answer:

389 feet away....about a block !

Step-by-step explanation:

If 0ne foot = 2.389x 10^5   miles

  2.389x10^5 miles / 'foot'

find the number of 'feet' to the sun for the model

   9.296 x 10^7  miles  / 2.389 x 10^5  miles/'foot'  = ~~389 feet  !!

Answer:

4

Step-by-step explanation:

By adding (+ / Plus) 2 and 2 together, like II + II, you get IIII. Otherwise, 4. Or "Four" as a word. You pronounce it just like you say "For" as in "For you". "Four" and "For" mean different things, but sound the same when said. Hope this helped! (lol i know this is a joke question)

According to picture we can see

The opposite angles formed by two intersecting  lines

The angles forming a right angle

The angles forming a straight line

Answer: Ok let's say the area is 100 sq cm because it is 10x10 square. Now if 1 cm is 2 ft then 10 cm is 20 ft. So 20 x 20 is 400 sq ft which is the actual area.

1 sq cm = 4 sq ft

Good luck!

Answer:

[tex]300\sqrt{2}[/tex]

Step-by-step explanation:

using pythagorean theorem we know that a^2+b^2=c^2 so [tex]300^2+300^2=c^2[/tex]

so [tex]c=+- \sqrt{300^2+300^2}[/tex] knowing that the line has to be positive you take the positive integer.
