Use the FOIL method: First, Outside, Inside, Last
3x(2x) = 6x²
3x(-4) = -12x
3(2x) = 6x
3(-4) = -12
6x² -12x + 6x-12
Combine like terms
-12x + 6x = -6x
6x² - 6x - 12 is your answer

Step-by-step explanation:
37 and 1/2 divided by 3/16 =
75/2 divided by 3/16 =
75/2 * 16/3 =
25*8 = 200 <--- 75 cancels 3; 16 cancels 2
Answer:
(8,150)
Step-by-step explanation:
Polar form is in,
(r,theta).
To find r, apply pythagorean theorem using both coordinates to find r.
To find theta, since we know the opposite and adjacent side, apply the tangent function.
Apply inverse tan function
Since the degrees have to be in between 0 and 360. Add 180 to -30.
So the answer is
(8,150).

<u>First we need to find all the interior angles. So we know that the inside of a triangle (all the angles added up) equals 180. So we need to equal all the inside angles to 180. </u>
2x + x + 60 = 180
<u>Now lets start to solve. First let's subtract the 60 from both sides. </u>
2x + x = 120
<u>Now we need to add the x's together. </u>
3x = 120
<u>Now we must divide the 120 by 3 to get x by itself. </u>
x = 40
<u>Now just replace the x with 40 to find each of the sides. I'm guessing the triangles are reflecting each other so </u><em><u><EHG would be equal to 80. </u></em>
<u>ALSO to check if 40 would be correct, add all the angles together in the same triangle and they SHOULD add up to be 180! Which they do! </u>
