a² - b² = (a - b)(a + b) , thus

x^{4} - 9

What is the answer, to this problem?
geniusboy [140]

Answer:

  b.  1.129 inch

Step-by-step explanation:

If the pan were completely filled, it would hold ...

  (7 in)(11 in)(2 in) = 154 in^3

of batter, or ...

  (154 in^3)(0.069 cups/in^3) = 10.626 cups

Since it is filled with only 6 cups, and the depth is proportional to the volume, the depth is ...

  depth/(2 in) = (6 cups)/(10.626 cups)

Multiplying by 2 in, we get ...

  depth = (2 in)(6/10.626) = 12/10.626 in

  depth ≈ 1.129 in
