The area of a rectangle is given by 3x^3+14x^2-23x+6
dmitriy555 [2]

The length of the rectangle is defined by (x-1)\cdot \left(x-\frac{1}{3} \right).

Geometrically speaking, the rectangle area is equal to the product of its base and its length. According to the statement the area is represented by a <em>third</em> <em>order</em> polynomial and width by a <em>first order</em> polynomial and, thus, length must be a <em>second order</em> polynomial.

By factor the polynomial we get the following roots:

A = 3\cdot x^{3}+14\cdot x^{2}-23\cdot x + 6

A = (x+6)\cdot (x-1)\cdot \left(x-\frac{1}{3} \right)

Then, the length of the rectangle is defined by (x-1)\cdot \left(x-\frac{1}{3} \right).

Does anyone understand this? show work please. thank you.

Answer:

You need to satisfy the equation.

I will solve one.

Step-by-step explanation:

x -2 < -5

now add + 2 to both sides to keep its value.

now we end up with x <-3, which means that the value of x should be less than -3 in order to satisfy the equation.

So -5 is an answer, -4 is an answer, but not -3 because it should be less than -3 not equal.

As for number 9 the dash underneath the less than symbol means that it can equal to.

Hope this helps.
