What is the length of EF
I will give Brainliest

950 will be the answer

hope this is helpful ^_^

im guesing 0 represents the like before you raise the height

the height of the slide is 10 feet higher then 0 because its off of the ground 10 feet

Step-by-step explanation:

Kayla should mark the level 3 whole tick marks to the left of the zero on the number line.  

This would mean the number is negative, for it is on the left of the zero. Another way to say this could be that the absolute value of -3 is three, for it is three whole tick marks from the zero.
