Answer: 
Step-by-step explanation:
Given
The ratio of the area of the similar triangles is equal to the square of the side of the corresponding sides
Suppose the corresponding side on figure A is 
On solving

The answer is B
A number line from negative 8 to positive 8 in increments of 1, with only whole numbers that are multiples of 2 labeled. Place point P at the third tick mark to the left of 0. Put point Q at the fifth tick mark to the right of 0.
Answer:

Step-by-step explanation:
Given expression,

=>
We see that
is common in both numerator and denominator
hence canceling out we get:-

Answer=
P = 2L + 2w
Subtract 2L
from each side: P - 2L = 2w
Divide each side
by 2 : (P - 2L) / 2 = w
You could also write it as (P/2 - L) = w
Both answers are the same.
