Kirsten and molly are on a 3-day bike ride. the entire route is 156 miles. on the first day, they bilked 64miles. on the second day, they bilked 45 miles. how many miles do they have left to bilke on the third day?

47 miles

Step-by-step explanation:

On the 3 day bike ride, they will ride 156 miles. After the first day of travelling 64 miles, they had 156 - 64 = 92 miles left. After the second day of traveling 45 miles, they had 92 - 45 = 47 miles left. They have 47 miles left on the third day.

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.
