At Oakton, Midlothian, and Jefferson high schools, the long jumpers employ different strategies for competition. At Oakton high school, the jumpers are very conservative. They are always very careful not to fault, which would result in a jump of 000. But as a result they all jump similar short distances. At Midlothian, the jumpers are very aggressive. They jump as far as they can, but they risk faulting. About half the jumpers get a score of 000 and half jump long distances. (A "long distance" is about twice as far as a "short distance".) At Jefferson, the jumpers strike a balance. They are fairly aggressive, but also careful. As a result, most jump medium distances, while one or two of them fault and jump 000.

answer: can and shows the work

step-by-step explanation:

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

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.
