The answer is B hoped it helped!! :)
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
=
=now
opening bracket
=
So
answer is :
B. 
Well remember this:
When the signs are the same it is positive
When the signs are different make it negative
When you are subtracting a negative and positive, it is going to be like adding
for example:
-9 - 5 = -14
You just add 9 and 5 to get 14, the signs are different so it is going to be negative. ONLY WHEN YOU ARE SUBTRACTING NEGATIVES
0.129 is the change in the growth rate of company.
According to statement
we have to find and compare the growth rate of the company weekly.
we use the growth rate formula is
GROWTH RATE = present - past / present
Substitute the values in this formula
1st week = 220-190 / 220
1st week = 0.136
2nd week = 252-220 / 252
2nd week = 32 / 252
2nd week = 0.126
3rd week = 290-252 / 290
3rd week = 0.131
4th week = 337 - 290 / 337
4th week = 0.139
5th week = 380 - 337 / 380
5th week = 0.113
6th week = 440 - 380 / 440
6th week = 0.136
7th week = 505 - 440 / 505
7th week = 0.128
Now we find the average value of growth rate
Average = 0.136 + 0.126+0.131+0.139+0.113+0.136+0.128 /7
Average = 0.909/7
Average = 0.129
So, 0.129 is the change in the growth rate of company.
