Write the definition as a biconditional statement. Two lines in the same plane that do not intersect are parallel lines.

Lines are parallel if and only if they are in the same plane and do not intersect.
Lines are skew if and only if they are in the same plane and do not intersect.
Lines are skew if and only if they are not in the same plane and do not intersect.
Lines are parallel if and only if there are two lines in the same plane.

Help please, I would truly appreciate it! :)

step-by-step explanation:

what are the statements? and what do you mean by "216 2 1 6"?

i would be happy to . most people on would also love to i'm sure. if you just want someone who has done algebra before and want a little more personal relationship than just begging strangers for , i can certainly be of service. i do have college myself so i might not be 24/7.

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.

answer:

it is 28 degrees colder in detroit than philadelphia.

step-by-step explanation:

what number adds to 21  

-7 + ? = 21

-7 + 28 = 21
