Answer:
so its 50+.25(x) = y or 140. x is amount of minutes y is total
What what what what what what
A²-169b² = a²-(13b)² --> difference of two squares
a²-(13b)² = (a-13b)(a+13b)
(7x + 2 + 8x^4) – (2x – 5 – 8x^4) + (3x + 5x^4)
= 7x + 2 + 8x^4 – 2x + 5 + 8x^4 + 3x + 5x^4
= 8x + 7 + 21x^4
= 21x^4 + 8x + 7
So the ratio of "The scale on a map indicates that 1 inch corresponds to an actual distance of 95 miles.", is...
Scale on map : Actual Distance
1 : 95 miles
We need to find the actual distance for 4.5 inches on the map.
4.5 : x
Just multiply 4.5 with 95 and you would get 427.5 miles.
So the actual distance between the two cities is 427.5 miles.
