Afootball team ran four plays. the first play lost 5 yards. the second play lost 9 yards. the third play gained 12 yards. the last play lost 8 yards. express the total gain or loss of yards as an integer

-10

Step-by-step explanation:

To find the the total gain or loss of yards, use an integer expression to write each play.

1st play = -5

2nd play = -9

3rd play = 12

4th play = -8

The expression is -5 + -9 + 12 + -8

                                -14 + 12 + -8

                                    -2 + -8

                                       -10

step-by-step explanation:

quartic functions has x = –1 and x = –2 as its only two real zeroes:

f(x) = a(x+2)(x+1)   a: real number

chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.
