Acar can travel 72 miles on 3 gallons of gasoline. how far can travel on 5 gallons of gasoline?

120 miles

Step-by-step explanation:

To solve, find the unit rate of miles per gallon.

72 / 3 = 24 miles per gallon.

This means on 5 gallons he can go 5*24 = 120 miles

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
