Joy is training for a triathlon. she runs a distance of 2x miles, cycles a distance of (x2 + 7) miles, and swims a distance of (x - 2) miles. which simplified expression is equivalent to the total distance, in miles, joy covers?
x2 + 3x + 5
x2 + 3x + 9
3x2 + 5
3x2 + 9

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
