A painter is using a 12-foot ladder to paint a house. The painter places the ladder 6 feet from the house. How high up the wall does the ladder reach?

You're gonna need to post the table

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)
