9 marshmallows and 6 graham crackers

Step-by-step explanation:

12:4, 8:4

12/3, 8/2, so divide by three and divide by 2, so 3*2 and 3*3 gives us 9 marshmallows and 6 graham crackers

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
