Item 8 a store hands out 900 reward cards. customers scan their cards in the store to find out what reward they receive. the probability that a customer receives a $25 gift card is 1/12. how many customers receive a $25 gift card?

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables
