Mzabc = 28°
explore the properties of angles and arcs
formed by two intersecting secants.
mac = 80°
1. find the difference of arc measures.
mac -- mde =
mde = 24°

Xto the second power plus 14x plus 48. what are the factors? we are doing factoring trinomials with a=1

1- 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.2- 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 the first question?

Which of the functions graphed below has a removable discontinuity?
