Answer:
w = 10
Step-by-step explanation:
6w+18-9w = -12
Combine like terms
-3w + 18 = -12
Subtract 18 from each side
-3w +18- 18 = -12 -18
-3w = -30
Divide each side by -3
-3w/-3 = -30/3
w = 10
Answer:

Step-by-step explanation:
c=6
Angle A= π/4
Angle B= π/3
Angle C = π - (π/4+π/3)= 5π/12
We want to determine side A.
Using Sine Rule




a=4.39
A(-3;1)
b(-6;0)
c(-5;-3)
d(-2;-2)
Surface are is length times height.
8*8=64
a cube has 6 sides
64*6=384
The figure is a cuboid.
Hence, parallel edges to AH are BD, PY, and MK.
Hence, the answer is A and B.
