23) A recipe for cupcakes calls for 6 cups of sugar. Shreya has already put in 3 cups.
How many more cups does she need to put
in?

Shreya must put in 3 more cups of sugar.

Step-by-step explanation:

Given that a recipe for cupcakes calls for 6 cups of sugar, and Shreya has already put in 3 cups, to determine how many more cups does she need to put in to complete the amount required by the recipe, the following calculation must be performed:

6 - 3 = X

3 = X

Therefore, Shreya must put in 3 more cups of sugar.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
