Answer:
Step-by-step explanation:
Step 1: 6(x^2-1) [(6x-1)/(6(x+1)]
Step 2: [6(X+1) (X-1) (6X-1)] / 6(X+1)
Explanation: Factor out the (x^2-1)
Step 3: (6X-1) (X-1)
Explanation: Cancel out common terms on the top and the bottom of the fraction.
Step 4: 6X^2 - 6X-X+1
Explanation: Multiply out and Simplify
Answer: 6X^2 - 7x+1
Answer:
3. angles forming a linear pair to sum to 180
4. Def of supplementary angles
62.4% x = 17.16 and the answer is 27.5.
