Answer:

-35

Step-by-step explanation:

-5 (x + 2) + 5 (x -5)

Expand:

= -5x - 10 + 5 (x - 5)

Expand once more:

= -5x - 10 + 5x - 25

Simplify:

-35

Answer:

(a) even: J, K, M, O; odd: L, N

(b) L and O are connected to J

Step-by-step explanation:

Count the edge ends that intersect each vertex. You get ...

J-2, K-2, L-3, M-2, N-3, O-4

These numbers are the <em>degree</em> of the vertex.

a) Vertices with even degree are J, K, M, O, since these have degrees of 2, 2, 2, and 4, respectively--all even numbers.

Vertices with odd degree are L and N, since these both have degree 3, an odd number.

b) The vertices that are adjacent to J are the ones at the other ends of the edges that intersect vertex J. One of those two edges connects to vertex L; the other to vertex O. J is adjacent to L and O.

c) When we counted edges in part (a), we found vertex N to be of degree 3.

In her art studio, Jamie wants the throwing wheel to be 3 feet from the sink, and the table to be both 5 feet from the sink and

oee [108]

I know my picture stinks, but it is possible. If you make it into a triangle shape, but move the table a bit closer to the throwing wheel (as shown) it works out great. If you ever get a problem like his again, just think outside the box for different solutions.
