If the water level at the lake continued to change at the same rate for 3 months in a row explain how you could estimate the total change in the water level at the end of the 3 months period.

  Multiply the 1-month change by 3 to get the 3-month change.

Step-by-step explanation:

You could add up the changes for the three months. Your problem statement tells you to assume they are the same:

  3-month change = (1-month change) + (1-month change) + (1-month change)

  3-month change = 3×(1-month change)

Multiplication was invented to simplify repeated addition.

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.

these sign is used to tell weather the number is greater or less than the number   <   or >     but this sign means its equal =
