Joe 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 eleventh to the total distance, in miles.

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)

I’m not gonna do that
