Answer:
<u>The correct answer is B. {-2,4}</u>
Step-by-step explanation:
Let's solve for x, this way:
x + 4/4 = x /x -2
(x + 4) * ((x - 2) = 4 * x
x² - 2x + 4x -8 = 4x
x² - 2x + 4x -8 - 4x = 0
x² - 2x -8 = 0
(x - 4) * (x +2) = 0
x - 4 = 0
x + 2 = 0
x₁ = 4
x₂ = - 2
<u>The correct answer is B. {-2,4}</u>
Answer:
Option A is correct.
Step-by-step explanation:
The first step in the construction of a square inscribed in a circle is to draw a diameter of the circle.
Then we have to draw perpendicular bisector of the diameter using a compass.
Therefore, the perpendicular bisector will be another diameter of the circle and both the diameters will meet at the center of the circle.
Now, join the points with straight lines in order where the two diameters meet the circle. And finally, we will get a square inscribed in the circle.
Hence, option A is correct. (Answer)
<span>Old Surface Area = 202 ft^2
New Surface Area = 1818 ft^2
Notice we have this ratio:
(new area)/(old area) = 1818/202 = 9
and how 3^2 = 9. This is no coincidence.
The old surface area is multiplied by 3^2 = 9 to get the new surface area
.
If you asked "What would the surface area of the prism be if each dimension were quadrupled?"
, then you would multiply the old surface area by 4^2 = 16 to get the new surface area So really thats how you would solve that </span><span />

Step-by-step explanation:
sine = opposite / hypotenuse
- sin y = 7/12
- y = arcsin (7/12)
- y = 35.69
