The boys at academy camp are working on math problems to prepare for a math competition. the camp leader has put a problem on the board for the students to work on. paolo does the following problem incorrectly. explain the error and redo the problem showing the correct answerpaolo's answer -0.43-0.2 = -0.23 

We don't actually know what the problem originally was, so we don't know what the error was or what the correct answer should be.

If the numbers on the left are given, and the problem is to find the number on the right, then ...

Paolo added 0.2 instead of subtracting it.

-0.43 -0.2 = -0.63 . . . . . correct answer

If the left and right numbers are given and the problem is to find the one in the middle, then ...

Paolo incorrectly calculated 0.43 -0.23, getting -0.2 instead of +0.2.

-0.43 +0.2 = -0.23 . . . . correct answer

If the problem is to find the term on the left, then ...

Paolo incorrectly added 0.2 and -0.23, getting -0.43 instead of -0.03.

-0.03 -0.2 = -0.23 . . . . correct answer

step-by-step explanation:

a rhombus is a parallelogram enjoying his symmetry.

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.
