Answer:
option (B) 20
Step-by-step explanation:
Data provided in the question:
Number of photographs initially sold = 20
selling price of first 20 photographs = $10 each
Therefore,
Revenue from 20 photographs = 20 × $10 = $200
Selling price of further photographs = $15
Let the number of additional photographs sold be 'x'
thus,
total revenue = $200 + $15x
now,
according to the question
80% of ($200 + $15x) = $400
or
0.80 × ($200 + $15x) = $400
or
($200 + $15x) = $500
or
$15x = $300
or
x = 20
Hence,
the answer is option (B) 20

Answer:
Solution given:
now
f(x)+g(x)=
....(1)
now
factoring x²+6x-40
we get
x²+10x-4x-40
x(x+10)-4(x+10)
(x+10)(x-4)
now substituting in equation 1 ,we get
f(x)+g(x)=
taking l.c.m

So
answer is :
B. 
Answer:
When 
Step-by-step explanation:
When 
is smaller than 
, the resulting value under the square root will become negative. Since it is impossible to take the root of a negative number, the expression is thus undefined, however, it can be represented with the imaginary number 
where =
