Negative one plus negative four

it would result into a negative number since they are both negative, however if you imply real math rules it would result in positive five since the signs change when a negative and a negative becomes a positive

Step-by-step explanation:

-5

Step-by-step explanation:

-4+(-1) A negative number added by another negative number will stay negative.( like a positive number by a positive will be positive.)

468

step-by-step explanation:

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.
