Question

Find the equation for the area, A, of the rectangle with a length of n-5 and a width of n-1.

A A=n(n-1)+5(n-1)
B n^2-5n+5
C n^2-6n+5
D n^2+5

Answer 1

the answer to this would be C

Answer 2

C.
`n^(2)`-6n+5

Explanation:

Area of a rectangle =l x w

A=(n-5)(n-1)

Use distributive property

`n^(2)`-n-5n+5

Combine like terms

`n^(2)`-6n+5
