Answer:
To simplify first factorize both the numerator and the denominator
For the numerator
5x² + 20xy + 20y²
Factor 5 out
5 ( x² + 4xy + 4y²)
Using a² + 2ab + b² = ( a + b)²
The numerator is
5( x + 2y)²
For the denominator
x² - xy - 6y²
Rewrite -xy as a difference
x² + 2xy - 3xy - 6y²
Factorize
We have the denominator as
( x + 2y)( x - 3y)
So we now have

We have the final answer as

Answer:
Perimeter = 10 cm
Area = 6.25 cm²
Step-by-step explanation:
So to find the Perimeter of the square, we'll use this formula :
Hence, the perimeter would be 10 cm .
We know that the formula of Area to find the square is,
Note : The answer would always be in cm².
Hence, the area of the square would be 6.25 cm².
<em>We are done !</em>
I hope this helps!

Answer:
0.9375sec.
Step-by-step explanation:
Using the motion formula: V= u - gt
At Max. Height, V=0, taking t=32ft/sec^2
Thus: 0 = 30 - 32t
32t = 30
t=30/32
t= 0.9375sec
Therefore,
it will take 0.9375seconds which is less than 1 second to reach maximum height, then the ball starts descending. Just after 1 sec, ball is below its maximum height and in downward motion.
