The answer is B! Ive past my test for this task.
Ratio is white socks / brown socks
There are 8 white and 7 brown
Ratio = 8/7
Step-by-step explanation:
(ax + b)² = a²x² + 2abx + b²
In this case, a = 1, so:
14 = 2b
b = 7
(x + 7)² = x² + 14x + 49
B is slowly and A is filling more quickly because the amount of water increases during a smaller period of time.
199, it rounds to 200 because it's closer to 200 than 100. It is also closer to 200 than to 190. And finally, 1 + 9 + 9 = 19
