Answer:
Cubic polynomial function with zeros 3,3 and -3 is 
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:
So, cubic polynomial function with zeros 3,3 and -3 is
The side length should be 7 because 7*7=49 and the area of a rectangle is A=length*width

Find the surface area of one hanging lantern
we know that
The surface area of a cone (hanging lantern) is equal to
we have
assume
substitute the values
step 2
Find the surface area of the three hanging lanterns
Domain of y = sqrt(x + 6) - 7 <br><br>
Finding domain is trying to check the following valid conditions <br>
<br>
condition 1: check for x such that the value in square root must greater or equal to 0 <br>(applicable here) <br>x + 6 >= 0<br>x > -6 ... this is the answer<br><br>
condition 2: check for x such that the divisor must not be zero <br>(not applicable here) <br><br>
condition 3(misc) : check some functions <br>for example ... log(0) is invalid...<br>
