hey girl hey, im sorry you have no answers so far. im looking for some answers too!!!
It takes the son one and half hours to clean the house. To find this you need the equations F+S=2 and F+1=S. (F=father and S=son) You take the F+1 and substitute it in for S in F+S to get F+(F+1)=2. Then you combined like factors, 2F+1=2, and simplify to get F=.5hr. After this you plug .5 in to F+1=S to get (.5)+1=S, meaning it takes the son 1.5 hour to clean the house.

Answer:
The area of the yard is;
5x^4 -2x^3+9x^2+50
Step-by-step explanation:
Here, we want to calculate the area of the yard
Mathematically, this can be calculated as the difference between the area of the plot and the base area of the house
So, we simply proceed to calculate a subtraction here;
Thus, we have this as;
5x^4 + 9x^2-4x -(2x^3-4x-50)
= 5x^4 + 9x^2-2x^3+ 50
Rearranging this, we have;
5x^4 -2x^3+9x^2+50
