9514 1404 393

Answer:

  B, C, D, E

Step-by-step explanation:

A square has all side equal, opposite sides parallel, and all angles equal (90°). Because all sides are equal, so are adjacent sides. All but the first and last descriptions apply to a square.

The first description is that of a trapezoid, which has exactly one pair or parallel sides. The last description is that of an isosceles (right) triangle, which has sides that are referred to as "legs."

Please help!!! I would like an explanation along with your answer. Thanks

Answer:

x = 12/13

BC = 140/13

Step-by-step explanation:

If A is the mipoint of BC, then AB is half of BC.

AB = BC / 2

8x − 2 = (3x + 8) / 2

16x − 4 = 3x + 8

13x = 12

x = 12/13

BC = 3x + 8

BC = 3 (12/13) + 8

BC = 36/13 + 104/13

BC = 140/13

Please help me on 17-18!<br> I have no clue on what to do on the problems at hand.

If you would have to graph x=7, you probably know that this is a vertical line at, well, x=7.

| x | = 7 is nothing more than two vertical lines, namely x=7 or x=-7, as you already wrote down.

| x | = -8 has no (real) solutions, so there is nothing to graph.
