23. 10c2 - 21c = -4c + 6

c = 2  or c  = -3/10

Step-by-step explanation:

23. 10c2 - 21c = -4c + 6

10*cc  - 21c  = -4c + 6

10cc  - 21c + 4c - 6 = 0

10cc - 17c - 6 = 0

c =  17/20  +  root (17*17 - 4*10 *(-6)) / 20

c = 17/20 + 23/20

c = 2  or  c = -6/20 = -3/10

if you use photomath right away it will give you the answer not like this app that you have to wait for people.
