Megan used 1/2 cup of almonds to make 4 cups of trail mix. Using this same proportion, how many cups of almonds would Megan need to make 9 cups of trail mix?

d.192

step-by-step explanation:

12*16=192

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)
