Question

The square of the quantity three less than a number n is seven.

a) n^2 - 3^2 = 7
b) n^2 - 3n = 7
c) n^2 - 3n + 7 = 0
d) n^2 + 3n - 7 = 0

Answer 1

The square of the quantity three less than a number n is seven. To represent this as an equation, we start with n and subtract 3 from it, and then square the result. The correct equation is (n - 3)^2 = 7.

Step-by-step explanation:

The square of the quantity three less than a number n is seven. To write this as an equation, we start with n and subtract 3 from it, and then square the result. So the equation becomes (n - 3)^2 = 7. The correct option that represents this equation is a) n^2 - 3^2 = 7.
