15 miles * 5280 ft/mile = 79200 ft
1 hour * 60 minutes/hr = 60 minutes
79200ft/ 60 minutes
1320 ft/min
Answer:
See below.
Step-by-step explanation:
No. Triangles Perimeter
1 14
2 18
3 22
We see from the table, after the first perimeter (= 14), with each increase of 1 in the number of triangles, the perimeter increases by 4.
As an equation it is P = 14 + 4(n - 1) where P = perimeter and n = number of triangles.
It is how much the x values can expand on a graph
3(2x-4)=2(x+4)
6x-12=2x+8
6x-2x=8+12
4x=20
x=20/4
x=5
If the solution of x is 3, then the solution of 6x would be 18, because 3*6=18. :)
