Answer:

3,3,3,3 ,-6, and -6.

Step-by-step explanation:

Given the polynomial function

f(x) = (x-3)^4(x+6)^2

To find the roots of given polynomial we put f(x)=0

(x-3)^4(x+6)^2=0

Then we put

(x-3)^4=0  and (x+6)^2=0

Now, we put each factor of (x-3 )equal to zero

x-3=0

x=3

x-3=0

x=3

x-3=0

x=3

x-3=0

x=3

Similarly , we put each factor of (x+6 ) equal to zero

Then we get

x+6=0

x=-6

x+6=0

x=-6

Multiplycity of 3=4

 Multiplicity of -6= 2.

Multiplicity of any number is defined as the number of repeatation of that number in polynomial function.

Therefore, the roots of given polynomial function are 3,3,3,3-6 and -6.

Please help, nobody is helping I need to find surface area
Reil [10]

Answer:

A) 147.6 sq m

Step-by-step explanation:

Separate the pyramided out into 4 triangles and add those

3 of them (sides) will be the same

A=h\frac{b}{2} \\A=10\frac{4}{2} \\A=20

This is one half of the side, multiply by 2 to get the area of the entire side, 40 square m.

The area of all 3 sides together is 40*3 = 120 sq m

For your base, your height will be 6.9 and your base is 4

A = 13.8  sq m

multiply by 2 again for the entire base

A=27.6 sq m

Now add both

120 + 27.6

Is 20x9x5 a associative or distributive property?
Oduvanchick [21]
It is neither. Distributive is like 20x9 20x5 then add those products. Associative is like (20x9) x5. You can however use both for this equation
