Answer:
x=-2,-3
Step-by-step explanation:
x^2+5x+6=0
(x+2)(x+3)=0
x+2=0
x=-2
x+3=0
x=-3
18 minutes 27 seconds = 1,107 seconds
1,107 / 3,600 = .3075 hours
26.2 / 1.3075 =

Answer:
Step-by-step explanation:
49/30 or 1 19/30
This is the difference of 2 squares
square root of a^6 = a^3
and square root of 25 b^2 = 5b so we get
(a^3 + 5b)(a^3 - 5b)
Thats the answer
The number of bacteria will modeled using exponential growth function, this is given by:
f(x)=a(b)^x
where
a is the initial amount
b=ratio of growth
x=time
Thus from our information we shall have:
f(x)=R(t)
a=1000
b=r
t=x
hence we shall model the situation by:
R(x)=1000(r)^t
Hence in 3 years time the population will be modeled by the function:
R(x)=1000(r)^3=1000r³
