Use the FOIL method to multiply the binomials. Assume any variable exponents represent whole numbers.
-$$( x + 4 ) ( x + 1 )$$
A) $x ^ { 2 } + 5 x + 5$
B) $x ^ { 2 } + 4 x + 4$
C) $x ^ { 2 } + 5 x + 4$
D) $x ^ { 2 } + 4 x + 5$

Using the FOIL method (First, Outer, Inner, Last) to multiply the binomials $(x + 4)(x + 1)$, we get: First: $x \cdot x = x^2$, Outer: $x \cdot 1 = x$, Inner: $4 \cdot x = 4x$, Last: $4 \cdot 1 = 4$. Adding these together, we get $x^2 + x + 4x + 4 = x^2 + 5x + 4$.
