Answer: One piece is 60 cm and the other is 100cm

Lets think, "x" as the length of each piece.

3 + 5 is 8. So,

x/160 = 3/8

x= 3/8*160

x= 60

--------------------------------------------------------------------------------------------------------------

x/160 = 5/8

x= 5/8 * 160

x= 100

Step-by-step explanation:

<em>3</em><em>:</em><em>5</em><em>=</em>

<em>3</em><em>×</em><em>5</em><em>=</em><em>1</em><em>5</em>

<em>5</em><em>×</em><em>3</em><em>=</em><em>1</em><em>5</em>

<em>3</em><em>/</em><em>1</em><em>5</em><em>×</em><em>1</em><em>6</em><em>0</em><em>=</em><em>3</em><em>2</em>

<em>the</em><em> </em><em>fir</em><em>s</em><em>t</em><em> </em><em>piece</em><em> </em><em>is</em><em> </em><em>3</em><em>2</em>

What is a cubic polynomial function with zeros 3,3 and -3? show your work.​
Brums [2.3K]

Answer:

Cubic polynomial function with zeros 3,3 and -3 is \mathbf{x^3-3x^2-9x+27=0}

Step-by-step explanation:

We need to find a cubic polynomial function with zeros 3,3 and -3.

If zeros of polynomial are: 3,3,and -3

we can write:

x=3, x=3, x=-3

Or

We can write:

x-3=0, x-3=0, x+3=0

Now, we can write them as:

(x-3)(x-3)(x+3)=0

Multiplying the terms, we can find the polynomial:

(x-3)(x-3)(x+3)=0\\(x(x-3)-3(x-3))(x+3)=0\\(x^2-3x-3x+9)(x+3)=0\\(x^2-6x+9)(x+3)=0\\x(x^2-6x+9)+3(x^2-6x+9)=0\\x^3-6x^2+9x+3x^2-18x+27=0\\x^3-6x^2+3x^2+9x-18x+27=0\\x^3-3x^2-9x+27=0

So, cubic polynomial function with zeros 3,3 and -3 is \mathbf{x^3-3x^2-9x+27=0}
