9 = 1 + 8x - 8
Add 8 to both sides:
17 = 1 + 8x
Minus 1 on both sides:
16 = 8x
Divide both sides by 8
2 = x
Hope it helped :)
The solution to the problem is as follows:
<span>cos2A - cos4A = -2 sin(6A/2).sin(-2A/2) = +2 sin(3A).sinA
and
sin4A - sin2A = 2 cos(6A/2).sin(2A/2) = 2 cos(3A).sinA
Hence RHS = (cos(2A)-cos(4A))/ (sin(4A)- Sin(2A)) = sin 3A / cos 3A = tan 3A = LHS

gcd = 6 ⋅ d
Step-by-step explanation:
We have that
6
d
^2 = 6 ⋅ d ⋅ d and 18
d = 3 ⋅ 6 ⋅ d hence the gcd = 6 ⋅ d

2 bags. She needs to buy 2 bags of 10 pounds of potting soil.
20-13=7
2 more bags will give Marunne's father all the soil he needs and 7 pounds left over.
