I need help please is for tomorrow):

Step-by-step explanation:

If a number gets increased by scale factor = k

Then k > 1

If the number gets decreased by a scale factor 'k'

Then 0 < k < 1

Let numbers gets increased by the scale factor = 2,

And decreased by the scale factor =

Numbers             Scale up by 2           Scale down by

   0.05                  0.05 × 2 = 0.1             0.05 × = 0.025

    7                       7 × 2 = 14                     7 × = 3.5

   13                      13 × 2 = 26                  

   25                     25 × 2 = 50                                

  102                   102 × 2 = 204              

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

the answer is c just got it on ed
