We know that x > 2 ( or : x ≠ +/- 2 )
We have to factorize the numerator and the denominator:
x² - x - 6 = x² - 3 x + 2 x - 6 = x ( x - 3 ) + 2 ( x - 3 ) = ( x - 3 ) ( x + 2 )
x ² - 4 = ( x - 2 ) ( x + 2 )
We have to factorize the numerator and the denominator:
x² - x - 6 = x² - 3 x + 2 x - 6 = x ( x - 3 ) + 2 ( x - 3 ) = ( x - 3 ) ( x + 2 )
x ² - 4 = ( x - 2 ) ( x + 2 )
Answer:
27.2 inches
Step-by-step explanation:
Given :
Refer the attached figure
ΔABC AND ΔEDC are right angled triangle at B and D respectively
So we will use trigonometric ratios :
IN ΔABC perpendicular = AB=20 inches and hypotenuse = AC=34 inches
IN ΔEDC perpendicular = ED=16 inches and hypotenuse = EC=x inches
Since ∠ACB = ∠ECD

⇒
Thus distance X the ball traveled after it bounces off the wall to get to the ending position =27.2 inches
