Answer:

168  which is not listed

Step-by-step explanation:

Do what is inside the brackets first. Subtract the two terms

52 - 10 = 42

Now multiply by 4

42 * 4 = 168 which is none of your answers. There must be more to the problem.

A certain connected graph has 68 vertices and 72 edges. Does it have a circuit?
OLEGan [10]

Answer:

Yes.

Step-by-step explanation:

If a graph G doesn't have a circuit, we must have that

|E(G)|=|V(G)|-1

where |E(G)| is the number of edges of the graph and |V(G)| the number of vertices. However, in this case it holds that

|E(G)|=72>68=|V(G)|.

Help plz with Algebra question I attached a file
astraxan [27]

Answer:

x=4.63

Step-by-step explanation:

Area = (1/2) (base) (height)

20 = (1/2) (x+4) (x)

40 = x²+4x

x²+4x-40=0

Put in quadratic equation:

x=\frac{-4(+/-)\sqrt{4^{2}-4(1)(-40) } }{2(1)}

x=\frac{-4(+/-)\sqrt{176} }{2}

x=4.63324958071 or x=-8.63324958071

Since x can't be negative in this case we take our answer to be 4.63324958071, which rounds to 4.63

I am Lyosha [343]
Going to put your function in slope-intercept form for the sake of easier input into Desmos.

y - 2 = - (x + 5)
y - 2 = - x - 5
y = - x - 5 + 2
y = - x - 3
