Steve and herb are choosing seats at the baseball stadium. the seats are numbers like a coordinate grid. steve chooses the seat at (3, 4). if herb does want to sit in the same vertical or horizontal row as steve’s seat, which seat should he choose?

a. (3,5)
b. (2,3)
c. (4,3)
d. (-1,3)

15 / 2 = 7.5

100 / 7.5 = 13.

the diagram shows you   triangle def with de=4, df=9 and de≠df≠ef.

the sum of the lengths of two triangles' sides are always greater than the length of the third side:

substitute sides lengths:

then 5< ef< 13 (option 3 is true).

def is a scalene triangle with all sides of different lengths (option 5 is true, option 2 is false).

answer: correct choices are 1, 3 and 5
