Two fewer than a number doubled is the same as the number decreased by 38. if n is "the number," which equation could be used to

Alona [7]

$\displaystyle \\ 
\text{We use the following equation:} \\ \\ 
 \frac{n}{2} = n - 38 \\ \\ 
We solve for n: \\ \\ 
 \frac{n}{2} = n - 38 ~~\Big| \times 2 \\ \\ 
n = 2 \times n - 2 \times 38 \\ \\ 
n = 2n - 76 \\ \\ 
2n - n = 76 \\ \\ 
\boxed{n = 76} \\ \\ 
\text{Verification: } \\ \\ 
\frac{n}{2} = n - 38 \\ \\ 
\frac{76}{2} = 76 - 38 \\ \\ 
\boxed{38 = 38 ~~~ Correct }$

What is the area of the following?<br> Height: 3x2 - 2x - 6<br> (4x)<br> (4x)<br> (4x)

mestny [16]

The area of the rectangle shown is expressed as 4x² - 2x - 6

The diagram is attached below:

Area of a rectangle = Length * width

From the diagram;

Length = 4x - 6

Width = x+1

Substitute the given parameters into the formula as shown:

Area = 4x-6(x+1)

Area = 4x(x) + 4x (1) - 6x - 6

Area = 4x² + 4x - 6x - 6

Area = 4x² - 2x - 6

Hence the area of the rectangle shown is expressed as 4x² - 2x - 6
