The area of his office according to the new blueprint is given by the expression below, where x is the side length, in feet, of the original square-shaped office.

x^2+15x

Which statement best describes the term 15x?

the area of the office according to the old blueprint
the width of the office according to the new blueprint
the area added to the office according to the new blueprint
the area of the office according to the new blueprint

Answer 1

The area added to the office according to the new blueprint

Explanation:

you're welcome

Answer 2

see the figure attached

we know that

the old blueprint is the square ABCD
Area=x*x=x²----------A1=x²

the new blueprint is the rectangle AEFB
Area=(x+15)*x----------> A2=x²+15*x

so

A2=A1+15*x

therefore

the answer is
the term 15x is the area added to the office according to the new blueprint
