Use the FOIL Method to Multiply the Binomials (4xn+11yn)(xn+9yn)\left( 4 x ^ { n } + 11 y ^ { n } \right) \left( x ^ { n } + 9 y ^ { n } \right)

Question 109

Multiple Choice

Use the FOIL method to multiply the binomials. Assume any variable exponents represent whole numbers.
- (4xn+11yn) (xn+9yn) \left( 4 x ^ { n } + 11 y ^ { n } \right) \left( x ^ { n } + 9 y ^ { n } \right)


A) 4x2n+47xnyn99y2n4 x ^ { 2 n } + 47 x ^ { n } y ^ { n } - 99 y ^ { 2 n }
B) 4x2n+47xnyn+99y2n4 x ^ { 2 n } + 47 x ^ { n } y ^ { n } + 99 y ^ { 2 n }
C) 4xn+2+47xnyn+99yn+24 x ^ { n } + 2 + 47 x ^ { n } y ^ { n } + 99 y n + 2
D) 4xn+47xnyn+99yn4 \mathrm { x } ^ { \mathrm { n } } + 47 \mathrm { x } ^ { \mathrm { n } } \mathrm { y } ^ { \mathrm { n } } + 99 \mathrm { y } ^ { \mathrm { n } }
