The area of a rectangular mirror is 15 7 16 square feet. The width of the mirror is 3 1 4 feet. If there is a 5 foot tall space on the wall to hang the mirror, will it fit?

Given:

Area of rectangle = [tex]15\dfrac{7}{16}[/tex] sq. feet.

Width of the mirror = [tex]3\dfrac{1}{4}[/tex] feet.

To find:

Whether it will fit on the wall whose length is 5 foot.

Solution:

We know that, area of a rectangle is

[tex]Area=length\times width[/tex]

[tex]\dfrac{Area}{width}=length[/tex]

Substituting the given values, we get

[tex]Length=\dfrac{15\dfrac{7}{16}}{3\dfrac{1}{4}}[/tex]

[tex]Length=\dfrac{\dfrac{15\times 16+7}{16}}{\dfrac{3\times 4+1}{4}}[/tex]

[tex]Length=\dfrac{\dfrac{240+7}{16}}{\dfrac{12+1}{4}}[/tex]

[tex]Length=\dfrac{\dfrac{247}{16}}{\dfrac{13}{4}}[/tex]

[tex]Length=\dfrac{247}{16}\times \dfrac{4}{13}[/tex]

[tex]Length=4.75 [/tex]

So, length of mirror is 4.75 feet which is less than 5 feet.

Therefore, the mirror will fit on the wall.

I WILL GIVE SOMEONE 40 POINTS TO ANSWER THIS COMPLETELY WITH COLUMS DONE WITH PROBLEMS SOLVED- You are going to design an advertisement for a new polynomial identity that you are going to invent. Your goal for this activity is to demonstrate the proof of your polynomial identity through an algebraic proof and a numerical proof in an engaging way! Make it so the whole world wants to purchase your polynomial identity and can't imagine living without it!

You may do this by making a flier, a newspaper or magazine advertisement, making an infomercial video or audio recording, or designing a visual presentation for investors through a flowchart or PowerPoint.

You must:

Label and display your new polynomial identity
Prove that it is true through an algebraic proof, identifying each step
Demonstrate that your polynomial identity works on numerical relationships
Warning! No identities used in the lesson may be submitted. Create your own using the columns below. See what happens when different binomials or trinomials are combined. Square one factor from column A and add it to one factor from column B to develop your own identity.

Column A Column B
(x − y) (x2 + 2xy + y2)
(x + y) (x2 − 2xy + y2)
(y + x) (ax + b)
(y − x) (cy + d)
