Answer:
12
Step-by-step explanation:
6(d+1)−2d=54
Here, we have to find the value of d
multiply (d+1) by 6
6×d + 6×1 - 2 d= 54
6d + 6 - 2d= 54
Now subtract 2 d from 6d
6d- 2d +6= 54
4 d+ 6=54
Now, by using transposition method,
+ 6 will be transferred from L.H.S to -6 to R.H.S
4 d = 54- 6
4d= 48
Now, divide 48 by 4
d= 48÷ 4
d= 12
Hence, the value of d is 12
Hence, the correct answer is 12

Answer:
B = 49.1°
C = 93.9°
c = 77.9
Step-by-step explanation:
Given:
a = 47, b = 59, and A = 37°
Required:
B, C, and c
Solution:
✔️To find B, apply the law of sines:
Plug in the values
Cross multiply
Divide both sides by 47
B = 49.0690779° ≈ 49.1° (nearest tenth)
✔️C = 180° - (A + B) (sum of triangle)
C = 180° - (37° + 49.1°)
C = 93.9°
✔️To find c, apply the law of sines:
Plug in the values
Cross multiply
Divide both sides by sin(49.1)
c = 77.8766982
c ≈ 77.9 (nearest tenth)

Answer:
an= 12 + (-6)(n-1)
Step-by-step explanation:
you should find two values: a1 and d
a1= first number =12
d= a number of the sequence mines the number of the sequence before the one you chose = 0-6 = -6
a1+(n-1)d= 12-6(n-1)
