Answer: Choice C) Britney is correct. Gabrielle multiplied -4 and -6 to get -24 but should have gotten 24

Both students used the FOIL rule correctly (FOIL stands for "first, outer, inner, last" to help remember how to multiply out two binomials), except of course Gabrielle's mistake getting -24. The FOIL rule is basically 2 applications of the distributive property. You can also use the box method to visually organize the terms. See the attached image for the box method.

Kim caught a fish that was 9/10 of a meter long. Doug caught a fish that was 2/3 as long as kim's fish
MA_775_DIABLO [31]

Kim caught a fish that was 9/10 of a meter long. Doug caught a fish that was 2/3 as long as Kim's fish. So, Doug caught a fish that was 3/5 meters long.

<h3>What is the fundamental principle of multiplication?</h3>

If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways

Kim caught a fish that was 9/10 of a meter long. Doug caught a fish that was 2/3 as long as Kim's fish.

Kim caught a fish of length = 9/10 m

Doug caught a fish of length = 2/3 as long as Kim's fish.

                                                 = 2/3 x 9/10

                                                 = 18 / 30

                                                 = 3/5

Thus, Doug caught a fish that was 3/5 meters long.

Stella [2.4K]
Your sequence appears to be geometric with a common ratio of 2. It can be described by
  a(n) = (-2 2/3)·2^(n-1)

_____
This can be written in a number of other forms, including
  a(n) = (-8/3)·2^(n-1)
  a(n) = (-1/3)·2^(n+2)
  a(n) = (-4/3)·2^n
