(5 * sqrt(x^7))^3
Recall sqrt(x^2)=x
So we get (5*x^6 )^3
5*3 is 25, 6*3 is 18 (and exponent to an exponent multiplies)
Therefore the answer is 25x^18
Every point on the line 3/7x -1 is a solution
Unless there is another line provided...
Answer:
23d + 45 = 137
Explanation:
Since it is $23 per day, that dollar amount must be associated with a variable that multiples it per day that it is rented. Finally, you need to add the one time $45. This equation can then be used to find how many days it was rented for.
23d + 45 = 137
23d = 92 (Subtract 45 from both sides)
d = 4 (Divide by 23 on both sides)
The rug-cleaning machine was rented for 4 days. You found this using the equation: 23d + 45 = 137
The cheapest service would be the year in which the mean was the lowest. In Year 4, the mean was the lowest.
The most consistent service would be the year in which the range was the lowest. In Year 3, the range was the lowest.
