Burt has a box he wants to wrap but needs to know how much wrapping paper he will need. He measured that the box has a length of 12 cm, width of 6 cm and a height of 7 cm. What will the SA be for how much wrapping paper that will be needed? Don't forget to show all work.

answer:   n ≤ -3 or n < -5

step-by-step explanation:

-5 + 2n ≥ -11

+5             +5

2n ≥ -6

2/2 ≤ -6/2

n ≤ -3

-6 - 10n > 44

+6           +6

-10n > 50

-10/-10 50/-10

n < -5

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

i got 10.28 but that rounds up to 10.3

answer: (3,11) is your answer.
