For this case we have that, by definition, the sum of the internal angles of a quadrilateral is 360 degrees. So:
We subtract 216 on both sides of the equation:
We divide between 4 on both sides of the equation:
Thus, the value of x is 36 degrees.
Answer:
36 degrees
Answer: X = 36.
Step-by-step explanation: There are 360 degrees in a trapezoid. Two angles are 108 degrees. 108 + 108 =216. 360 minus 216 is 144. 2x + 2x = 4x. 144 divided by 4 is 36. Therefore, x =36.

Answer:
6 (y + 8) (y - 1)
Step-by-step explanation:
Factor the following:
6 y^2 + 42 y - 48
Factor 6 out of 6 y^2 + 42 y - 48:
6 (y^2 + 7 y - 8)
The factors of -8 that sum to 7 are 8 and -1. So, y^2 + 7 y - 8 = (y + 8) (y - 1):
Answer: 6 (y + 8) (y - 1)
PS: it's really helpful to pose the question correctly 6 y^2 + 42 y - 48 NOT
6y 2 - 48 + 42y
Answer:
6 (y + 8) (y - 1)

Why cut it like this? We find the highest number that divides both 20 and 10, in this case it's 10. Then, we can cut squares with the lenght of 10 cm. But we have a rectangle with the area of 20*10=200 cm^2 , and we cut squares of 10*10=100cm^2. 200/100=2. So we cut 2 squaresAlso, you could say that it's because the simmetry line cuts the rectangle in 2 other simetrical rectangles, which in this case, happen to be squares.
