Answer:
The side length is multiplied by 
Step-by-step explanation:
we know that
The area of the original square is equal to

If the area is doubled
then
The area of the larger square is

Remember that
If two figures are similar, then the ratio of its areas is equal to the scale factor squared
Let
z ----> the scale factor
x ----> the area of the larger square
y ---> the area of the original square
so

we have




------> scale factor
therefore
The side length is multiplied by 
That sucks they should've worked harder
Answer:

Step-by-step explanation
We have given that equation of line a+4b=0
⇒4b= -a
⇒
slope of line = 
⇒
is negative therefore it lies into 4th quadrant
By, Pythagoras theorem 
by putting value of P= -1 & B=4
the value of
with the given condition 
i.e.
∈ (3π/2, 2π)
now, 
You are correct there is no pattern
