Using the quadratic formula to solve x2 + 20 = 2x, what are the values of x?
a.1 plus-or-minus startroot 21 endroot i
b. negative 1 plus-or-minus startroot 19 endroot i
c.1 plus-or-minus 2 startroot 19 endroot i
d.1 plus-or-minus startroot 19 endroot i

answer: the common difference is -0.10

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

8 is smaller than 9 which is the third side.

hope this : )

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.

your answer is  

d.
