Vaselesa [24]

Answer:

The area of the yard is;

5x^4 -2x^3+9x^2+50

Step-by-step explanation:

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
