At first it increased by 25% and then decreased by 40%
Makovka662 [10]

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%

Use the method of completing the square to transform the quadratic equation into the equation form (x + p)2 = q.
ryzh [129]

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:

6+12x+3x^2=0

Rearranging the Equation:

3x^2+12x+6=0

Dividing the equation by 3 gives us:

x^2+4x+2= 0

Subtracting 2 from both sides

x^2+4x+2-2=0-2

x^2+4x=-2

Here

x=a\\4x=2ab\\Then\\4x=2(x)(b)\\b=\frac{4x}{2x}\\

b=2

So,

Adding (2)^2 on both sides

(x)^2+4x+(2)^2=-2+(2)^2\\(x+2)^2=-2+4\\(x+2)^2=2

The correct answer is: A) (x + 2)^2 = 2
