Answer:
~ -4x+4y+10
Explanation:
~ We have to collect like terms such as all the x’s, y and the normal numbers.
~ Then add like terms together: x-5x, 4y plus nothing, 3+7
~ After adding them, you should get -4x+4y+10.
Answer: fg
and
Domain: All real number. All real number or 
Explanation:
fg means product of two given function f(x) and g(x)
where,
and 
Now, we have to find fg
So, fg=
Substitute f(x) and f(x)

Using distributive property simplify above expression and we get,

We can see it is cubic polynomial. So, domain of cubic polynomial is all real number.
Domain: All real number or 
Answer:
The initial population size is of 58.
The population size of the specie after t years is given by:

Step-by-step explanation:
Population size of the specie:
The population size of the specie after t years is given by:

Initial population size
This is P when
, that is,
. So

Rounding to the nearest number, 58
The initial population size is of 58.
The third quadrant are both negative numbers so the answer is B.
Trapezoid Area = (Base1 + Base2) (h/2)
so A = (3x + 5x )(6x/2)= 24x^2
