Geometry Equation of parallel and perpendicular lines please help asap will mark brainliest (provide work)

C. i believe it is (5×(-20))+(100×(0.7))

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)
