My father is 47 years old. I am x years old. a. How old will my father be in y years’ time?
b. How old will I be in y years’ time?

your father 47+y You x+y

Step-by-step explanation:

Your father is 47 + y years old after y years

You will be x + y years old after y years.

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.
