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.
