For this type of function, the domain is all real numbers. A function with a fraction with a variable in the denominator. To find the domain of this type of function, set the bottom equal to zero and exclude the x value you find when you solve the equation. A function with a variable inside a radical sign.
Part A:it would be 32 dollars because 60 and 30 percent off is 42 dollars subtract 10 is 32
part b: yes it would be different the new total would be 35 because if you subtract 10 first it would be 50 then 30 percent off is 35
So, if you multiply each polynomial by eachother, the area of the patio is 3x^2+16x+5, and the area of the yard is 48x^2+36x+6. If you subtract patio from the yard, the remaining value is 45x^2+20x+1, which is the remaining area of the yard, so the correct answer is D
