Answer: 12%
Step-by-step explanation:
Let the original salary be Rs a
Salary after increase = a + 40% of a
= a + 40a/100
= 140a/100
= 14a/10
= 7a/ 5
Salary after Decrease = 7a/5 - 20% of 7a/5
= 7a/5 - 20× 7a / 100 × 5
= 7a/5 - 7a/25
= ( 35a - 7a) / 25
= 28a/25
Absolute increase = 28a/25 - a
= 3a/25
Percentage = 3a/25 ×100 / a
= 3 × 4
= 12%
Answer:
2x - 20
Step-by-step explanation:
-20/2 + 2x - 10
-10 + 2x - 10
2x - 20
To answer this question we need to add 39.95+1.95=41.9
Then just subtract: 90.75-41.9=48.85
The answer is 48.85.

The correct answer is: A) (x + 2)^2 = 2
Further explanation:
We have to convert the equation into simplest form to complete square
Given equation is:
Rearranging the Equation:
Dividing the equation by 3 gives us:
Subtracting 2 from both sides
Here
b=2
So,
Adding (2)^2 on both sides
The correct answer is: A) (x + 2)^2 = 2
