The answer is choice A.
We're told that the left and right walls of the cube (LMN and PQR) are parallel planes. Any line contained in one of those planes will not meet another line contained in another plane. With choice A, it's possible to have the front and back walls be non-parallel and still meet the initial conditions. If this is the case, then OS won't be paralle to NR. Similarly, LP won't be parallel to MQ.
<span>Math Term Definition. Algebraic Expression. An algebraic expression
is a mathematical phrase that can contain ordinary numbers, variables
(like x or y) and operators (like add,subtract,multiply, and divide).
Here are some algebraic expressions: a + 1.</span>
This is I suppose basic addition. Addition is a mathematical process of combining or joining something to something else. The word "total" indicates that the addition will be used. If the doctor ran for 55 hours and the mom for 52 hours, by using the addition it will be:
55
+ 52
______
107 hours in total.
107 hours converted in days will be 4 days and 4 hours. SInce 1 day contains 24 hours you now divide 107 hours by 24 hours to get its equivalent to days.
Number 1 is x=8!!
2 is pretty confusing so I hope someone else can answer two as I have answered 1!
