Answer:
it will take her 40 seconds to finish the race.
3/8 per minute, would make it 1/8 every 20 seconds. since she only has 2/8 of a mile left to go, 20 seconds +20 seconds = 40 seconds
(if you needed how long it takes her to run the whole race, it's 2 minutes 40 seconds, which would make her the fastest mile runner in the world)

Answer:
-3
Step-by-step explanation:
Step 1: Solve (-2+(-1))^2/3 3
            1. -2+(-1) = -3
            2. (-3)^2 = 9
            3. 9/3 = 3
Step 2: Solve (-4)^2-17 -1
            1. 3/-1
Step 3: Simplify 3/-1 = -3. I hope this helped and please don't hesitate to reach out with more questions!

The triangle on the left appears to be congruent with the triangle on the right.  If this observation is actually valid, then x+7 = 2x-5.  12=x  Yes, I realize that this doesn't match any of the answer choices, 'tho the 4th choice is the only one that contains "12."  Would you please share the instructions for this problem.
