If it's $50 a meter, then the answer is:
x is the cost per meter
16x + 12x + 8x + 2x
But that answer is 5,075,020,100 and that is a ridiculously high number. I hope this helps even if it doesn't answer the question.
Answer:
relative minimum
Step-by-step explanation:
From f^''(x) = 12x we can take the integration to find out what f'(x) is:
Furthermore, we can substitute x = 1 for f''(x) to find out whether it's positive or negative
f''(1) = 12*1 = 12 > 0
So if x=1 is a critical point of f'(x) and f''(x=1) > 0 then that point is a relative minimum point
Answer:
( x - 3 )( x + 9 )
Step-by-step explanation:
The first thing we want to do here is to break the expression into groups. This will help us factor out common terms, that will later be grouped - our resulting, factored expression.
x² + 6x - 27 - Break the expression into groups,
( x² - 3x ) + ( 9x - 27 ) - Factor out x from the expression " x² - 3x. " Respectively factor out 9 from the expression " 9x - 27. "
x( x - 3 ) + 9( x - 3 ) - Now this contains the shared expression " x - 3, " and hence can be broken down further through grouping.
Factored Expression: ( x - 3 )( x + 9 )
Answer:
The fourth option.
Step-by-step explanation:
2 x 2 = 4
3 x 2 = 6
8 x 2 = 16
9 x 2 = 18
14 x 2 = 28
