Answer:
q = -6
Step-by-step explanation:
8(q + 6)
= (8×q) (8×6)
= 8q + 48
8q = -48
q = -48/8
q = -6
5 lbs equals 80 ounces because 1 lb is 16 oz
Answer:
<h2>only x = 39</h2>
Step-by-step explanation:
x + 6 = 45 <em>subtract 6 from both sides</em>
x + 6 - 6 = 45 - 6
x = 39
Cos(2x) = cos^2(x) - sin^2(x) - cos(x)
but sin^2(x) = 1 - cos^2(x)
cos(2x) - cos(x) = cos^2(x) - (1 - cos^2(x) ) - cos(x)
cos(2x) - cos(x) = cos^2(x) - 1 + cos^2(x) - cos(x)
cos(2x) - cos(x) = 2cos^2(x) - 1 - cos(x)
cos(2x) - cos(x) = (2cos(x) + 1)(cos(x) - 1)
I think this is what you have asked for.
