the area of a rectangle is x-16/x. If the width of a rectangle is x/4+1, find an expression to represent the length.

The expression to represent the length

Step-by-step explanation:

Given

We know that The formula for the area of the rectangle is:

Thus, the length of a rectangle

Length = Area ÷ Width

Cancel the common factor: (x+4)

Thus, the expression to represent the length

step-by-step explanation:

what grade level is this? need to know so i can look in my old textbooks!

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
