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:
74
x

185
Step-by-step explanation:
Answer:
x = 9
Step-by-step explanation:
2x - 1 + 1 = 17 + 1
2x = 18
(2x=18)/2
x = 9
Answer: 0.01% in decimal form=0.0001 and in fraction form=1/10000
Step-by-step explanation:
Step 1 To convert the percentage in decimal form.
A percentage is a ratio expressed as a fraction of 100.
So, 0.01% means 0.01 out of 100.
Therefore,
0.01%= 0.01/100
0.01%= 0.0001
Step 2: Convert the decimal in fraction form.
Remove the point by dividing by 10000
0.01%= 1/10000
The meaning of the result is that helium account for less than one part per 10000 parts of Earth’s atmosphere gases.
