Use the distance formula below to answer the question: d=sqrt ((x_(2)-x_(1))^2+(y_(2)-y_(1))^2) What is the distance between (7,-2) and (3,1) square
Multiply both sides of the equation by the same expression: square times ((1)/(a)-(1)/(d))=square times bc The resulting equation is: c=square
Apply the distributive property to the expression. $100(0.07a+0.02b)=\square $
