D. It is equal to the measure of segment HI.

Answer 5

If you can help with any of these, it would be very appreciated :)

Answer 6

For #1: Point E is on the left side of zero thus meaning negative. So now just count left from zero and you get -17.

For #2: You have point F located at -10 and Point I located at 14 and then it asks you for the length of the two points together so The distance between 0 and -10 is 10 cm and the distance between 0 and Point I is 14 cm. Thus just combine both of them (10+14) to get 24 cm.

For #3: It asks what is true about the LENGTH of segment EF so you know any length of something can't be negative (For example, can't be -6 feet tall). It can't be less or equal to segment HI because EF is longer (HI = 6, EF = 7). So finally, since the length of EF is 7 its positive.

Hope this helps and Good Luck :)
