Your answer is wrong, the real answer is y=64
Answer:
From the given options, option D is the only choice that contains (w-5).
Step-by-step explanation:
Given the expression

Breaking the expression into groups

Factor out 'w' form w²+4w = w(w+4)
Factor out 'w' from -5w-20= -5(w+4)
so

Factor out common term: w+4

Thus, the factors are: (w+4) and (w-5)
Therefore, from the given options, option D is the only choice that contains (w-5).
Answer:

C is your answer
Step-by-step explanation:

If the areas of two equilateral triangles are 27 yd² and 75 yd², then the ratio of these areas is 27/75 = 9/25
If the ratios of the areas are 9:25, then their similarity ratio and the ratio of their perimeters is √9:√35 = 3:5.
