9x^2(2x^2 + 8x) = 18x^4 + 72x^3
Answer:
2w + 3y - 1
Step-by-step explanation:
(2x+2)/y = 4w + 2
isolate x:
2x+2= y(4w + 2)
2x = y(4w + 2) - 2
x = y(2w + 1) - 1
x = 2wy + y - 1
x = 2w + 3y -1
Step-by-step explanation:

b. Since csc theta = 1/sin theta, we can multiply both sides by sin theta and you will end up with

which is an identity.
Answer:
40 degrees
100-60=40
Step-by-step explanation:
The angle x is in another angle that looks like 100 and 100 minus 60 is 40.
Hope this helps and if it is correct.
