Alona wants to prove that the base angles of any isosceles triangle are congruent. She draws ∆DEF, as shown, and then draws segment EG, the median of segment DF. Use the drop-down menus below to complete Alona’s proof that base angles of an isosceles triangles are congruent.

What is the solution of log2  (3x  -  7)  =  3? 4 5

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis. 3- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in part b?
