Check the picture below.

(x+6)^2=x^2+12^2\implies (x+6)(x+6)=x^2+144 \\\\\\ \stackrel{F~O~I~L}{x^2+12x+36}=x^2+144\implies 12x+36=144\implies 12x=108 \\\\\\ x=\cfrac{108}{12}\implies x = 9

Each shape is 1 whole. What fraction is represented by the shaded part of the model?
lubasha [3.4K]

Answer:

\frac{2}{1}

Step-by-step explanation:

Each shape is 1 whole.

In the given image, there are 4 parts in each shape.

The shaded part in the first shape is 4.

The fraction of the shaded part in the first shape

                                            =\frac{Number of shaded part}{Total part of the fraction}=\frac{4}{4}

The shaded part in the second shape is 4.

The fraction of the shaded part in the second shape

                                           =\frac{Number of shaded part}{Total part of the fraction}=\frac{4}{4}

The shaded part of the model =\frac{4}{4}+\frac{4}{4}

                                                  =\frac{1}{1}+\frac{1}{1}

                                                  = \frac{2}{1}

Hence, the fraction represented by the shaded part of the model is \frac{2}{1}.

Write an equation for the cubic polynomial functior
d1i1m1o1n [39]

So, the cubic polynomial function is x^3-10x^2+31x-30=0

No, none of the roots have multiplicity.

Step-by-step explanation:

We need to write an equation for the cubic polynomial function

whose graph has zeroes at 2, 3, and 5.

Zeros mean:

x=2, x=3 and x=5

or

x-2=0, x-3=0 and x-5=0

Multiplying all the factors:

(x-2)(x-3)(x-5)=0\\(x-2)(x(x-5)-3(x-5))=0\\(x-2)(x^2-5x-3x+15)=0\\(x-2)(x^2-8x+15)=0\\x(x^2-8x+15)-2(x^2-8x+15)=0\\x^3-8x^2+15x-2x^2+16x-30=0\\x^3-8x^2-2x^2+15x+16x-30=0\\x^3-10x^2+31x-30=0\\

So, the cubic polynomial function is x^3-10x^2+31x-30=0

No, none of the roots have multiplicity, A root has multiplicity if it appears more than 1 time. Like if (x-1)^2 is a root then 1 has multiplicity 2
