whats the answer to this equation:

4+8x+2.2-10x

if the lenght of a rectangle is 7 inches and the width is (x+2) inches. write an expression in simplest form that represents the area of a rectangle?

4+8x+2.2-10x

use the commutative property of addition to rearrange things a bit:

4+2.2 + 8x-10x

for the rectangle, area = width * length, so it would be

7(x+2)

To find the answer to the equation 4 + 8x + 2.2 - 10x, we can combine the like terms:

4 + 2.2 + (8x - 10x)

4 + 2.2 - 2x

6.2 - 2x

So, the simplified form of the expression is 6.2 - 2x.

Now, to find the expression that represents the area of a rectangle with a length of 7 inches and a width of (x + 2) inches, we can use the formula for the area of a rectangle, which is length x width:

Area = Length x Width

Area = 7(x + 2)

Now, we can simplify this expression:

Area = 7x + 14

So, the simplified expression that represents the area of the rectangle is 7x + 14.

To solve the equation 4+8x+2.2-10x, we need to simplify and combine like terms.

First, let's combine the terms with x:

8x - 10x = -2x

Now, let's combine the constant terms:

4 + 2.2 = 6.2

Finally, let's put it all together:

-2x + 6.2

So, the simplified expression for the equation 4+8x+2.2-10x is -2x + 6.2.

Now, let's write an expression in simplest form that represents the area of a rectangle.

The area of a rectangle is calculated by multiplying its length by its width. In this case, the length is given as 7 inches, and the width is represented as (x+2) inches.

So, the expression for the area of the rectangle is:

Area = Length * Width
= 7 * (x+2)
= 7x + 14

Therefore, the expression that represents the area of the rectangle in simplest form is 7x + 14.
