what is it called when the measure of each exterior angle of a triangle is equal to the sum of remote interior angles

4should be the last one n=4

B. because the 7 represents "seven times", x represents "a number", 12 represents "plus twelve", and -4 represents "minus four"

If i think this is what your asking, he should look at the grams or pounds/ounces and compare the to their cost then max can identify which one is proportional and which is not ( i think xd)
