Why do we use the quadratic formula as opposed to trying to solve using factoring

Sometimes there is no apparent way to factor it by hand /(the factors are decimals or imaginary). To try and factor these problems is nearly impossible in your head.

I’m confused on this one
Ghella [55]

In a parallelogram, the opposite angles will be congruent to each other.


In this parallelogram, angles B and C are congruent, and angles A and D are congruent.


We will work on angles B and C first. Set the two angles to equal each other:


12x + 6 = 6x + 66


Subtract 6 from both sides:


12x = 6x + 60


Subtract 6x from both sides:


6x = 60


Divide both sides by 6 to get x by itself:


\boxed{x = 10}


x will equal 10.


Set angles A and D to equal each other:


54 = 3y


Divide both sides by 3 to get y by itself:


\boxed{y = 18}


y will equal 18.


The x and y values that make this quadrilateral a parallelogram will be x = 10, and y = 18.

Question
denpristay [2]
V= π r^2 h

r= radius
h= height

If the radius was 10 ft and the height was 12ft then the answer be about 3769.91.

However if it was reversed and the radius was 12ft and the height was 10 ft then the answer would be about 4523.89.

3769.92≈ π 10^2 12

or

4523.89≈ π 12^2 10

Wing figures, solve for x. Complete parts (a) 80° 53​
Korolek [52]

Answer:

x = 25°

Step-by-step explanation:

Applying,

Sum of the angle in the triangle = 180°

From the diagram,

First angle of the triangle = 55° (vertically opposite angles are equal)

Second angle of the traingle = 180-80 = 100° (sum of the angle in a straight line)

Third angle of the triangle = x

Therefore,

x+55+100 = 180

x+155 = 180

x = 180-155

x = 25°
