A) How many lakhs are there in (i) 1 million
b) How many crores are there in (i) 10 million
c) How many arabs are there in (i) 1 billion
a) How many millions are there in (i) 20 lakh
b) How many billions are there in (i) 30 arab
(ii) 5 million
(ii) 40 million
(ii) 20 billion
(ii) 5 crore
(ii) 2 kharab

The answer is below

Step-by-step explanation:

a)

i) 1 lakhs =  100000, therefore:

1 million =

ii) 1 lakhs =  100000, therefore:

5 million =

b)

i) 1 crore = 10 million. therefore:

10 million =

ii) 1 crore = 10 million. therefore:

40 million =

c)

i) 1 arab = 1 billion, therefore:

1 biilion =

ii) 1 arab = 1 billion, therefore:

20 biilion =

d)

i) 1 lakhs =  100000, therefore:

20 lakhs =

ii) 1 crore = 10 million. therefore:

5 crore =

e)

i) 1 arab = 1 billion, therefore:

30 arabs =

ii) 1 kharab = 100 billion, therefore:

2 kharab = 2 * 100 billion = 200 billion

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
