okay, the question is...
18. The distance between point A and B is 5times Squareroot 5 units. If point A is -4,-7 and point B is x,3 whats the X?
i think ur supposed to put it in standard form but ive tried it but i got confused and didnyt know what to do next
oh and i plugged everything into the distance formula and guessed that x is 1 and it worked but i want to why its 1 and stuffs
