In mathematics, a polynomial<span> is an expression consisting of variables (also called indeterminates) and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables. An example of a </span>polynomial<span> of a single indeterminate x is x</span>2<span> − 4x + 7.</span>
        
             
        
        
        
(2x³ - 5x² + 8)(x + 3) = ?
First step is to distribute.
2x^4 + 6x³ - 5x³ - 15x² + 8x + 24
Now combine like terms.
2x^4 + x³ - 15x² + 8x + 24
This is your answer, since you can't simplify any further or solve it without some more information.
        
             
        
        
        
As we could "drag" these together, we could then do it the easy way.
  56
+56

-------
168
------------------------
Or we could also do the following:
56

3:
6

3= 18.
Carry the one. 
5

3 = 15+1 (which was carried). = 16
(16+8) = 
168
 
        
        
        
That answer was (B)................
        
             
        
        
        
Answer:
128 feet
Step-by-step explanation:

So now we will substitute the values of T and π into the equation.


Divide both sides by 6.28

Square both sides.

Multiply both sides by 32
