x = -3 or x = -2
Step-by-step explanation:
x² + 5x + 6 = 0
(x + 3)(x + 2)
x = -3 \/ x = -2
Rahul use addition property of equality in step 2.
Solution:
The image of the question is attached below.
Step 1:
combine like terms together.
To make the denominator same multiply and divide 2x by 5.
Step 2:
By addition property of equality, add on both side of the equation.
Step 3:
Step 4:
Multiply by on both side of the equation.
Hence Rahul use addition property of equality in step 2.
Sum of interior angles=(n-2)180
3060=(n-2)180
3060/180=n-2
17=n-2
n=17+2
n=19..
Digit in ones place- 8
Digit in tenths place- 2
As, v=√2as
Squaring both sides,
v²=2as
∴ s= v²/2a
