t (x+4)(2x+3)=? (x+4)(2x+3)=? (x+4)(2x+3)=? (x+4)(2x+3)=? First multiply the first term of each binomial in the parentheses: Multiply the two outer terms of each parentheses: Multiply the two inner terms of each parentheses: Multiply the last term in each set of parentheses: Write the answers on one line: Write the final answer on the next line: (x+y)(2x+3y)=2x²+5xy+12 1. (11x + 11) (11x + 10) =22x +21
2. (9x + 9) (3x + 3)
3. (8x + 11) (5x + 11)
4. (9x + 7) (6x + 4)
5. (11x + 5) (-11x + 12)
6. (8x + 11) (-3x + 6)
7. (6x + 3) (-5x + 2)
8. (7x + 7) (5x - 4)
9. (-10x + 11) (7x + 5)
10. (-9x + 5) (-10x - 6)
11. (8x - 13) (20x + 11)
12. (16x - 19) (8x - 8)
13. (18x - 20) (-12x - 6)
14. (10x - 11) (-14x + 9)
15. (-20x - 12) (-19x - 15)
16. (-14x + 11) (-9x + 19)
17. (-7x - 11) (19x - 14)
18. (6x + 7) (20x - 9)
19. (12x - 13) (-12x + 12)
20. (16x + 13) (-8x + 15) Then combine like terms (x+4)(2x+3)=2x²+ 3x+2x +12 Hi!!!!!
