It’s 101 because 72 and -29 have a difference of 101
Answer:
there is not a complete question here ...
is not in a denominator to rationalize
if it were you would multiply the rational expression (the fraction)
by 
the result (in the denominator would end up being "2 -1"
which is 1
Step-by-step explanation:
Answer:
Bottom right graph is the correct answer
-- Take. -5 . -- Add 12. to it. -- To the result, add 10. --- From that result, subtract 7 . -- The current result is the value of the expression.
Little tip ** if u r going from a larger shape to a smaller shape, the scale factor is going to be a proper fraction....a number less then 1 but greater then 0
BC = 66......EF = 11.......66 times what is 11
66x = 11
x = 11/66 reduces to 1/6
so 66 * 1/6 = 11
now compare the other sides...
42 * 1/6 = 7.......looks like AC and DF
72 * 1/6 = 12...looks like Ab and DE
so ur multiplying every number in the big triangle by 1/6 , and getting the measures of the little triangle....so ur scale factor is 1/6 <==
