29. ms. alvarez wants to determine the
seventh graders' preferences for the
location of the end-of-year field trip.
which of the samples is
representative
of the population?
udente in me alvarez's

The asnwer is C since the second one is infront of a negative change all the signs of ur 2nd trinomial thil will give you (7x2-4x+3) now add common like terms in the 2 trinomials 2x2 with 9x2 -9x with -4x and 2 with 3 to get 9x2 -13x+5

Hope this helps
