Answer:
x³ - 10x² + 31x - 30
Step-by-step explanation:
Given
(x - 2)(x - 3)(x - 5) ← expand the second pair of factors using FOIL
= (x - 2)(x² - 8x + 15) ← distribute
= x³ - 8x² + 15x - 2x² + 16x - 30 ← collect like terms
= x³ - 10x² + 31x - 30
 
        
             
        
        
        
Let's start with the fact that this is a function.  Each element of Set A is paired with exactly one element of Set B.
This makes Set A the set of inputs and Set B the set of outputs.
There are a lot of other boxes to pick from, so I'm not sure what else you'd need to pick to make your answer correct.
 
        
             
        
        
        
The definition of a coefficient is the number BEFORE the variable. So in 76x^2, the coefficient is 76.<span>

Answer:
520 feets 
Step-by-step explanation:
The height of the building, h can be obtuined using trigonometry ;
From the attached diagram, opposite side = 300 feets ; height, h = adjacent side
Hence, 
Tan θ = opposite / Adjacent
Tan 30° = 300 / height
0.5773502 = 300 / height
Height = 300 / 0.5773502
Height = 519.615
Height = 520 feets
