Leibniz was making zweibelkuchen for lunch. he puts 3 4/5 cups of flour in the bowl then added another 2 2/3. how many cups of flour did leibniz
use?

6 7/15

Step-by-step explanation:

Add the whole numbers separately = 5

Then deal with fractions, find common denominator (15)

12/15+10/15=22/15

Simplify 22/15= 1 7/15

Combine whole numbers and fractions 6 7/15

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
