Answer:
k = 4 + 5.10i , 4 - 5.10i
Step-by-step explanation:
8k - k^2 = 42
k^2 - 8k + 42 = 0
Completing the square:-
(k - 4)^2 - 16 +42 = 0
(k - 4)^2 = -26
k- 4 = +/-sqrt26
k = 4 + sqrt26 or 4 - sqrt26
k = 4 + 5.10i , 4 - 5.10i

hmm, increases by 2
an=a1+d(n-1)
a1=first term
an=nth term
d=common differnece
increases by 2 and starts with 2
a1=2
d=2
an=2+2(n-1)
15th apartment/collumn
a15=2+2(15-1)
a15=2+2(14)
a15=2+28
a15=30

Answer:
x= 4.3125
Step-by-step explanation:
2^2 = 16x - 65
4= 16x- 65
+65 +65
69 = 16x
69/16 =16x/16
4.3125 = x
