Write a polynomial in standard form that represents the area of the shaded region.


A rectangle. Its length is labeled 2 x minus 9 and its width is labeled x plus 5.

Answers

Answer 1

Answer:

2x²+x-45

Step-by-step explanation:

Answer 2

In standard form the area of the rectangle is -

A = (2x² + x - 45) square units.

What is function?

A function is a relation between a dependent and independent variable. We can write the examples of functions as -

y = f(x) = ax + b

y = f(x, y, z) = ax + by + cz

Given is to write a polynomial in standard form that represents the area of the shaded region which is rectangle whose length is labeled (2x - 9) and its width is labeled (x + 5).

We can write the area of the rectangle as -

A = (2x - 9)(x + 5)

A = 2x(x + 5) - 9(x + 5)

A = 2x² + 10x - 9x - 45

A = 2x² + x - 45

Therefore, in standard form the area of the rectangle is -

A = (2x² + x - 45) square units.

The width of a rectangular room is 80% of its length. If the length of the room is 20 meters, what is the area of the room? A= length x width

Answers

Answer:320ft^2

Step-by-step explanation:

80% of 20 is 16, because 80% is 4/5 and 20 divided by 5 is 4, multiplied by 4 is 16. Area is L x W, so 16 times 20 is 320, and don't forget unit of measurement, ft^2 for area

A=320^2!
Length x width = area
