Yes; if you look at both terms, they both have a common factor of 3x, therefore, this expression can be simplified as 3x(5x-9).
(5y+6y)+(4x+8y)+(1z-5y)=
5y+6y+4x+8y+1z-5y=
14y+4x+1z

First, find the area of the large rectangle (25*18=450) then find the area of the small square (7.5^2=56.25) finally subtract the small square from the large rectangle
