The area of the rectangle is 18x-12 square inches. The width is 6 inches, as shown. Write an expression in simplest form that represents the length of the rectangle (in inches)

Respuesta :

Answer:

Length = 3x - 2  inches

Step-by-step explanation:

The area of a rectangle is found by the genral formula:

Area = Length * Width

Now, we are given the algebraic expression for AREA and also know that width is 6 inches. So we put it into the formula and get:

Area = Length * Width

18x - 12 = Length * 6

Now, we let Length be "l" and solve for this variable. Steps shown below:

[tex]18x - 12 = Length * 6\\18x - 12 = l* 6\\18x-12=6l\\l=\frac{18x-12}{6}\\l=\frac{18x}{6}-\frac{12}{6}\\l=3x-2[/tex]

Thus, the simplest form of expression for the length is:

Length = 3x - 2
