6x-9-2(1-x) = x-9
6x-9-2+2x = x-9 | -x
7x -11 = -9
7x = -9+11
7x = 2
x = 2/7

We need to distribute first before we try to get x on one side.

6x-9-2+2x=x-9
Let's add like terms.

8x-11=x-9
Let's subtract x from both sides.
7x-11=-9
Let's add 11 to both sides.
7x=2
Divide.
2/7=x

So, x=2/7.

Answer:

Edges: 6

Faces: 7

Vertices : 6

Step-by-step explanation:

3 Dimensonal (3D) shapes are shaped such that have faces, edges and vertices. From the numbers of faces, edges and vertices a 3D image has, you can tell or determine the type of solid shape it is.

Face: A face is the flat surface of a solid figure. Faces of 3D shapes comes in various forms such as triangles, rectangles, and pentagons.

Edge: An edge is defined as the straight line where two faces are connected to each other.

Vertices or a vertex: This can be defined as the point where edges connect or meet.

The 3D image in the question has :

6 Edges, 7 faces and 6 Vertices

Perform the indicated opera<br> 6) g(n)= n2 - 1<br> h(n)= 4n+1<br> Find (g. h)n)
DaniilM [7]

(g.h)(n)\,\,is\,\,4n^3+n^2-4n-1\\

Step-by-step explanation:

We are given:

g(n)=n^2-1\\h(n)=4n+1

We need to find (g.h)(n)

Finding (g.h)(n)

(g.h)(n)=g(n).h(n)\\ (g.h)(n)=(n^2-1)(4n+1)\\ (g.h)(n)=n^2(4n+1)-1(4n+1)\\ (g.h)(n)=4n^3+n^2-4n-1\\

So, (g.h)(n)\,\,is\,\,4n^3+n^2-4n-1\\

What is the geometric mean of 4 and 10
GalinKa [24]

Answer: 6.3

Step-by-step explanation:

The formula for geometric mean is given as :

G.m = \sqrt{pq}

Therefore , the geometric mean between 4 and 10 will be :

G.m = \sqrt{4(10)}

      = \sqrt{40}

      = 2\sqrt{10}

     = 6.3
