Let a=(1,5,−1)a=(1,5,−1), b=(−3,6,−5)b=(−3,6,−5), c=(0,4,−9)c=(0,4,−9), and d=(4,3,−5)d=(4,3,−5). find the area of the parallelogram determined by these four points, the area of the triangle abcabc, and the area of the triangle abdabd.

Step-by-step explanation:

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
