Answer:
2nd tank
Step-by-step explanation:
The rate of filling, in gallons per minute, is found by dividing gallons by minutes.
<u>Tank 1</u>
(3/4 gal)/(2/3 min) = (3/4)(3/2) gal/min = 9/8 gal/min
<u>Tank 2</u>
(5/8 gal)/(1/2 min) = (5/8)(2/1) gal/min = 10/8 gal/min
10/8 gal/min is more than 9/8 gal/minute.
The second tank is filling faster.

Answer:
D. (x² -2x -3) +(-x² +4x +2)
Step-by-step explanation:
The tiles on the first row model (x² -2x -3).
The tiles on the second row model (-x² +4x +2).
If the difference is being modeled, it will show as ...
(x² -2x -3) -(-x² +4x +2) = (x -2x -3) +(x² -4x -2) . . . . . matches none
If the sum is being modeled, it will show as ...
(x² -2x -3) +(-x² +4x +2) . . . . . matches D

As is often the case, you can select the correct answer without even any understanding of the question. You can do that because the correct answer is <em>the only one that is a true statement</em>. All of the other answer choices are incorrectly "simplified."
