DGFH is a rhombus where E is the midpoint of the lines GE and GF
please look at the image

is a monomial (since it is all connected by multiplication) and since it is in the degree of 2, that makes it a quadratic.
-2 is a constant (since it doesn't have variables) and it is a monomial (since it is all connected by multiplication)
3x-9 is a binomial (since it has two terms, not connected by multiplication) and since it has x in the power of 1, that makes it a linear equation.
Finally,

-6x + 9 is a trinomial (since it has 3 terms connected by either addition or subtraction) and since the degree of the polynomial is 2, that makes it a quadratic.
This is a proportion problem
Info needed: there is 36 inches in a yard
1/36= x/18
Cross multiply and divide
18 x 1= 18
18 divided by 36= .5 or 1/2
Answer is 1/2
