4x + 5 = 6x – 7 solve for x

Mathematics
1 answer:
Hoochie [10]3 years ago
8 0

Answer:

x = 6

Step-by-step explanation:

4x + 5 = 6x - 7 subtract 4x from both sides

5 = 2x - 7 now add 7 to both sides

12 = 2x finally divide both sides by 2

x = 6

Find the surface area of the triangular prism (above) using its net (below).
hodyreva [135]
This is quite simple, first, you must find the area of each shape, since the form of the prism is currently 2D.

Formula for (Area of Rectangle)= length x width

Formula for (Area of Triangle)= 1/2 base x height

Now, we have the formulas. Let’s get started!

(Identification) There are 3 rectangles and 2 triangles. 2 rectangles are of the same size and 2 triangles are of the same size.

Triangles~ the base is 6 and the height is 4.

1/2 (6 x 4) = 12

However, there’s two triangles. (of the same size)

12 x 2 = 24

Rectangles 1 and 2~ the length is 5 and the width is 7

5 x 7 = 35

However, there’s two rectangles. (of the same size)

35 x 2 = 70

Rectangle 3~ the length is 6 and the width is 7

6 x 7 = 42

There’s only one of these.

Now we add all the areas of the shapes together!

24 + 70 + 42 = 136

The surface area is 136.

Find the product.<br> (z + 3i)(z − 3i)
Doss [256]

Answer:

First, we use distributive property:

(z+3i)(z-3i)=z^2-3zi+3zi-9i^2

Now, remember that i^2=-1, then

z^2-3zi+3zi-9i^2=z^2-9(-1)=z^2+9

Then,

(z+3i)(z-3i)=z^2+9

A squirrel runs 23 feet down a hill to eat acorn then runs 23 feet up the hill write a integer the represents the squirrels fina
Sindrei [870]

Assuming the top of the hill is 0.

Squirrel begins at 0 = 0

Squirrel runs down 23 feet = 0 - 23 = -23

Squirrel runs up 23 feet = -23 + 23 = 0

An integer that represents the squirrel's final position is 0.

Hope this helps!! :)
