Brut [27]3 years ago

Since coefficient of x^2 is prime and both second and third term are positive, it must be in form (3x+_)(x+_).

There is three possibles for these blank spaces;
1,4
2,2
4,1

Because coefficient of second term is 13 = 1+12 = 1+3*4, these blank space should be 1,4

So your answer is (3x+1)(x+4)

Hope this makes sense.

as x is direct to y hence

x∝y

also given x∝z combine these two equation we get

x∝y*z

now insert b as constant

x=b*y*z

as given x=20, y=3 , z=4 putt in above equation we get

b=20/3*4 =5/3 =1.666

The bird population on an island is declining at a rate of 2.2% per year. If the population was 3500 in the year 2009, which is
Vinil7 [7]
Given:
2009 : 3,500 population
decrease of 2.2% per year. 
100% - 2.2% = 97.8%

2014 - 2009 = 5 years

3,500 * (0.978)^5 = 3,500 * 0.89473 = 3131.57

The bird population in 2014 will be 3,131.57 or 3,132.

Identify the remainder when x3 - 3x2 - 9x is divided by x - 6.
kiruha [24]

Let p(x) be any polynomial of degree greater than or equal to one and let 'a' be any real number. If a polynomial p(x) is divided by x - a then the remainder is p(a). Hence by the remainder theorem, 0 is the remainder when x3 + 3x2 + 3x + 1 is divided by x + 1.
