To answer this problem, we group the first the like terms, in this case, the terms 3/m2 and 16/m2. The difference between these two terms -13/m2. Hence, the overall expression is m - 13/m2 - 9/m + 4.
The question is incomplete. Below you will find the missing part of the question.
How many rabbits were there after x years? Write a function to represent this scenario.
rabbits were there after x years.
The function form is
The number of rabbits released each year is 8.
During 0 year, there will be 8 rabbits;
During year 1, the number of rabbits will be 8+8 = 16, i.e. 8×2¹ = 16
Similarly, during the year 2, the number of rabbits will be 16+16 i.e. 8×2² = 32
So, according to the pattern we can say that the function would be

Answer:
This is the concept of geometry, we are required to calculate for the length of the sides of the rhombus; we know that a rhombus is a compressed square, this implies that all the sides are equal;
If one of the angles is 110° the other angle will be:
180-110=70°
thus using the cosine rule we can find the side lengths as follows;
c^2=a^2+b^2-2ac Cos C
thus
let side a=b=x in
shorter diagonal=c=4 in
C=70°
substituting this into the formula we get:
4^2=x^2+x^2-2*x*x Cos 70
4^2=2x^2-2x^2(0.3420)
16=2x^2-2x^2(0.3420)
dividing through by 2 we get;
8=x^2-0.3420x^2
8=0.6580x^2
x^2=12.15843
getting the square root of both sides get:
x=sqrt(12.15843
x=3.4869)
x=3.5 (1 d.p)
the length of the sides is 3.5
