Answer:
50 meters per day
Step-by-step explanation:
Since p = x² - 7, you can substitute/plug in p for x² - 7
So:
(x² - 7)² - 4x² + 28 = 5
(p)² - 4x² + 28 = 5 You can factor out -4 from (-4x² + 28)
p² - 4(x² - 7) = 5 Plug in p
p² - 4p = 5 Subtract 5
p² - 4p - 5 = 0 Your answer is C
I answered on paper hope that is alright with you. I just find it easier for math problems. That slash means two numbers cancel each other out. What's in the box is the answer and the proof that it's right is underneath.

Answer: 14.7 (Rounded)
Work: So since (2 x 10) / 1/3 is in parentheses, I'm going to to that first. And since (2 x 10) is in parentheses in a parentheses, I'm going to do that multiplication first. After doing the multiplication, I get 20, and I'm going to divide it by 1/3 since it's in the parentheses. After dividing, I get 6.666..., But I'm going to round it to 6.7. Then, I'm going to add 6.7 by 8, and I got 14.7
