Between the time lko woke up and lunchtime the temperature rose by 11 degree then by the time he went to bed the temperature dropped by 14

-3

Step-by-step explanation:

This question is asking you to find the difference in temperature

So, we start off with +11 degrees

If the temperature drops by -14 degrees, out equation should look like this:

11-14

Therefore the answer is -3 degrees because 11-14 is -3

I hope this helps :)

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.
