Answer:

B. 77%

the students that studied in the 4-5 hour range scored in the 70s. the ones that studied in the 6 hour range scored in the 80s.

I'd put 5 1/2 hours at around 80%, but the closest answer is the 77%

Komok [63]

Answer:

2x^2 - 2

Step-by-step explanation:

FOIL:

First outer inner last.

So we take (x-1) and (2x+2) and multiply the two first terms together.

2x^2

Next, we do the two outer terms.

2x^2 + 2x

Inner is next.

2x^2 + 2x - 2x

Then the last two terms in the equation.

2x^2 + 2x - 2x - 2

Then simplify:

2x^2 - 2
