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

question 109

Multiple Choice

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

• A) \(4 x ^ { 2 n } + 47 x ^ { n } y ^ { n } - 99 y ^ { 2 n }\)
• B) \(4 x ^ { 2 n } + 47 x ^ { n } y ^ { n } + 99 y ^ { 2 n }\)
• C) \(4 x ^ { n } + 2 + 47 x ^ { n } y ^ { n } + 99 y n + 2\)
• D) \(4 \mathrm { x } ^ { \mathrm { n } } + 47 \mathrm { x } ^ { \mathrm { n } } \mathrm { y } ^ { \mathrm { n } } + 99 \mathrm { y } ^ { \mathrm { n } }\)
