Question

4. Examine the figure below and answer the questions that follow. Be sure to write your answers in standard form and write the degree and classification for each answer.

A contractor is putting in a wall in an office building to partition the room into two smaller rooms. The image above shows a 2-dimensional representation of a wall with a cut-out for a door.

Answer 1

1. Create the expression that represents the area of the wall space only using the dimensions shown above. Show your work.
2. The contractor is trying to design a scale model of the wall to show the buildings manager. To create this scale, he will have to divide the the area of the wall as calculated in Part A by 4xy4. With the polynomial in standard form, divide the first term only by 4xy4. Then divide the second term only by 4xy4. Show your work for the division of each term by 4xy4 separately.
3. If a window with the area of 12xy4 was placed on this wall, what would be the new area of the wall space left? You must show all work and calculations to receive credit.

Answer 2

where's the image for #4

Answer 3

1. What is the area?

This one is easy. Do the area of the whole wall, minus the area of the door:
\[[(5x^{2}y^{3})^{3} * (4y^{2})^{3}] - [4y^{4} * 3x]\]

Answer 4

Simplify:
\[[(5^{3}x^{2(3)}y^{3(3)}) * (4^{3}y^{2(3)})] - [4(3)y^{4}x]\]

Answer 5

What's the next step in simplifying?
