How do I solve this ?

I think u are right

but I am not 100% sure

i think its

{x|x *greater than or equal symbol* 6}

step-by-step explanation:

what grade level is this? need to know so i can look in my old textbooks!

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
