Answer:
sin(x)-cos(x)
Step-by-step explanation:

Simplify the denominator:

Simplify the numerator:

Divide the fractions: <u>(a/b)/(c/d) = (a * d)/(b * c)</u>:

Use the identity: <u>2cos(x)sin(x) = sin(2x):</u>

Cancel out the common factor (sin(2x)):
-cos(x) + sin(x)
Simplify:
sin(x) - cos(x)
Answer:
It will be $5 per square yard
Step-by-step explanation:
The answer is b. Great job! here ill show you the work.
15x +90 > 270
move constant to the right side and change its sign, like this:
15x>270-90
then subtract the numbers
15x>180
lastly, divide both sides by 15.
hope this helped!
