Write a polynomial for the given real-world situation. If the length of a rectangle is 3x^2-4x+5 and the width is 2x + 1, write and simplify a polynomial expression for the area of the rectangle. 3 points for mathematical process and 2 points for correct answer.

Step-by-step explanation:

Given that:

Length of a rectangle =

Width of rectangle =

To find:

Simple polynomial expression for finding the area of rectangle.

Solution:

First of all, we should know about the formula for finding the area of rectangle. Then we should know how to multiply two polynomials.

Formula for area of a rectangle in terms of its length and width is:

Putting the given values:

Here, we can use the distributive property of multiplication for finding the value of the above multiplication expression.

Therefore, the multiplication of above polynomials can be written as:

Therefore, the answer is:

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !

income. 10x+1300

expenses 3x+(1800+1500)

expenses 3x+3300

to break even:

income = expense,

10x + 1300 = 3x + 3300,

solve for x.
