Let's look at the corresponding ratios:

And we see that the three aren't equal.
Hence, $\Delta ABC$ and $\Delta EDC$ are not similar.
It could be anything they are both variables.
I believe is your answer
Because u plug in -2 to all x
F(x)= (-2)^2-9(-2)+2
F(x)=4+18+2
F(x)=24
1/3 x 60 = 20 mins
Carl walks the dog for 20 mins in the morning.
1/2 x 60 = 30 mins
Carl walks the dog for 30 mins in the afternoon.
20 + 30 = 50 mins
Carl walks the dog for 50 mins a day.
50 x 7 = 350 mins
Carl walks the dog for 350 mins a week.
Answer: 350 mins.
Answer:
A
Step-by-step explanation:
