The waitress gets 45/75 = 3/5 of the tips
so waitress gets 3/5 * 350 = $210
True cus i don’t remember but it’s true
Please type this as 2(sin 2x)^2=2 <span>2sin^2 2x=2 is confusing.
Reducing this expression: (sin 2x)^2 = 1
Taking the sqrt of both sides, sin 2x = plus or minus 1
If sin 2x = 1, then 2x must be pi/2 or 3pi/2, and so x must be pi/4 or 3pi/4.
Now you do this for sin 2x = -1.</span>
Correct answer is third option ---C in edge
2(x^2+6x+9) = 2(x+3)^2
So after divided by (x+3), answer will be:
2(x+3)
