1) When it says more than, then you have to switch it so it will be 7n + 1 instead of 1+7n.
2) Because you then have to subtract by 5 you have to put the 7n + 1 in parentheses so it reads (7n + 1) - 5
3) And then to evaluate you just have to substitute n for 6
4) 7 * 6 = 42; 42+1 = 43; 43-5 = 38
5) The answer to this expression would be 38

Answer:
A.
Step-by-step explanation:
Since the denominators are the same we just have to combine the top.
Combine alike terms.
put that over our denominator.
The function p(x) = x^3 is a polynomial. Here the “variable”, x, is being raised to some constant power. The function f(x)=3^x is an exponential function (the variable is the exponent).
Exponential functions tend to get very big very quickly, and though they start out smaller than polynomial functions, they will always eventually become bigger. Notice that the two functions meet at x = 2 and x = 4.

gs used in 180 mile=10 gallons
gas used in 1 mile=10/180=1/18
gas used in 450 mile=1/18×450=25 gallons
Answer:
The correct answer is C.
Step-by-step explanation:
Since the Cosmic Pool company's pool's length is 8ft longer than the width, you can immediately rule out choices A and B, since their <em>widths</em> are greater than their <em>lengths</em> by 8, and not vice versa. This leaves choices C and D. The perimeter of a quadrilateral's formula is 
, which means the length plus the width and multiplied by 2. Using this formula, you can infer that the perimeter is 
= 
= 64ft, so choice C is the correct answer.
