Tessa has nine children and hires two babysitters at a time. Tim charges $15 per hour with the first hour free, and Yu charges $10 per hour plus a flat fee of $20.
Write an expression for Tessa's total cost, and say what
the variable represents. If they both work 8 hours,
what's Tessa's total cost

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.

the correct answer is x/3+10≥32

hope this !
