The answer is k=8 (4,6/8,7/12,8)
Answer:
60cos(25)=54.378467222199
The answer is 20.
5*10-5*6=50-30=20
Answer:

Step-by-step explanation:
+6x-5=0
we divide the coefficient of the X by half :
in this case: 6/2 = 3 , then we do the following
The result obtained is raised to square power: 3^2=9
we sum and subtract by 9 to maintain the balance of the equation:
+6x+9-9-5=0
we have:
-9-5=0
= 14
lets apply square root on both sides of the equation:

we know:

so we have:
abs(x+3)=
from where two solutions are obtained

finally we have:

Answer:
29 :)
it is 29 because 29 falls under all the prime number characteristics
