Answer:
cos 60° = one half because the angles are complements
Step-by-step explanation:
3(x+4) = 3(x) + 3(4) = 3x+12
3x+2x-4 = 5x-4
Part A) $520
Part B) 13.33% - Divide 520 by 39
Part C) $20.80 Divide 520 by 100, then multiply by 4

Answer:
<em> The simplified answer is
</em>
Step-by-step explanation:
For the given expression: (− 1/x )× 1−x/1+x × x/x^2−1
we need to simplify it
<em>
= (x+1)×(x-1)</em>
eliminating x and x-1 from the given equation we get
The value of x can't be zero
As we can't divide zero by zero
The value of x can't be one
As we can't divide zero by zero
<em> The simplified answer is
</em>
B because it goes up by the evens
