Answer:
Step-by-step explanation:
Given expression is,
(2x - 1)² + 2(2x - 1) = (2x - 1)(2x + 1)
To prove this identity we will take the left hand side of the equation and will prove equal to the right side.
(2x - 1)² + 2(2x - 1) = (2x - 1)(2x + 1)
4x² - 4x + 1 + 4x - 2 = (2x - 1)(2x + 1)
4x² - 1 = (2x - 1)(2x + 1)
(2x - 1)(2x + 1) = (2x - 1)(2x + 1) [Since a² - b² = (a - b)(a + b)]
Answer:

Step-by-step explanatibecause its congruent to a suplementary angle
Answer:
3rd option
Step-by-step explanation:
There are three wholes and 1 fourth which is 1/8 simplified so first improper fraction, CHECK!
The three wholes are all equal to 12 then there is another 1 fourth so 12+1=13 CHECK TOO!!!
(YAY WE SOLVED IT!)
The answer would be 50,000
