The area of a rectangle is represented by the polynomial 3x3+14x2-23x+6. The width of the rectangle is represented by the expression x+6. Find the expression that represents the length of the rectangle.

Step-by-step explanation:

Given that,

The area of a rectangle is,

The width of the rectangle, b = (x+6)

We need to find the expression for the length of the rectangle. We know that, the area of a rectangle is given by :

A = lb

Where

l is the length of the rectangle

Put all the values,

So, the length of the rectangle is equal to .

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
