Answer:
6n-13
Step-by-step explanation:
Since the question given is -7+6(n-1)
-7+6(n-1)
Open the bracket first
-7+6n-6
Collect like terms
-7-6+6n
-13+6n
Which can also be written as
6n-13
So C(n)=6n-13
Answer:
20.6693
Step-by-step explanation:
the expression is 27a^3 or (3a)^3
4 miles represent one inch on the map.
This is because since they are 8 miles apart, and 2 inches in the map, and you want to find out how many miles per inch. You divide 8 by 2 because you want to divide how many miles by how many inches so that you can get 2 parts. That's how you get four.
Now that you cut 8 miles into two parts, you have halves, and half of eight is 4. And 1 inch represents that half since 1 + 1 equals 2 and 4 miles represents each of the two parts since 4+4 equals 8.
252=28 x length x 1/2
252=28 x 1/2 x length
252=14 x length
252/14=length
18 inches= length
