Answer:
Solution on Screen
Step-by-step explanation:
It's okay don't worry
7c+ 12= -4c+ 78
⇒ 7c+ 4c= 78 -12 (inverse operation)
⇒ 11c= 66
⇒ c= 66/11 (inverse operation)
⇒ c= 6
Final answer: c= 6.
Answer:
k<3.5 or k>3.5
Step-by-step explanation:
k²-7k+12.25>0
(k-3.5)²
k²-7k+12.25
k²-2k·3.5+(√12.25)²
(k-3.5)²
k-3.5<0 or k-3.5>0
k-3.5 or k-3.5
