Directions: Old Mother Hubbard is baking cookies so her cupboards won’t be bare anymore! She bakes 109 cookies in all. She bakes the cookies on 4 cookie sheets. Each cookie sheet is arranged into equal rows and columns, but not every cookie sheet has the same number of rows and columns.

Using digits 0-9, at most once, how might the cookies be arranged on the cookie sheets?
(_ x _) + (_ x _) + (_ x _) + (_ x _) = 109

### Hint

Since you’re only using 8 of the digits 0-9, which might you not use? What are the possible combinations of factors that could be used on each cookie sheet? What are the possible combinations of products that could add to 109? How can you organize your trials to eliminate repeating the same combination?

Answer 1: ( 6 x 8)+ (7 x 4) + (3 x 5) + (9 x 2) = 109
Answer 2: (4 x 8) + (7 x 2) + (3 x 6) + (9 x 5 )= 109
** There are probably more correct answers.

Directions: Using the digits 1 to 9 at most one time each, place a digit …

1. 9×8=72
7×3=21
5×2=10
1×6=6
72+21+10+6=109 😀

2. (4×3)+(7×2)+(3×6)+(9×2)=109

3. (6×8)+(7×4)+(3×5)+(9×2)=109

4. Danitza Marenco

(6×8)+(7×4)+(3×5)+(9×2)=109 is what i got

5. 9×5+3×8+4×7+2×6=109

6. 5×5, 5×5, 4×7, 4×7,

7. (7X5)+(6X6)+(8X3)+(2X7)=109

8. 4×9 5×8 7×3 6×2 is 109.

9. 6X8=48 9X2=18 7X4=28 3X5=15 total is 109

48+18+28+15=109

10. 5×8 + 7×3 + 4×9 x 6×2=109

11. (7×5)(6×6)(8×3)(2×7)=109

12. Scarlett Salaz

6X8=48 9X2=18 7X4=28 3X5=15 total is 109

48+18+28+15=109

13. （5*9）+（3*8）+（3*5) + (5*5)=109
45+24+15+25=109

14. (6 x 8= 52)
(7 x 5= 35)
(5 x 2= 10)
(4 x 3= 12)

52+35+10+12=109

15. (4 x 8) + (7 x 2) + (3 x 6) + (9 x 5 )= 109

16. Answer 1: ( 6 x 8)+ (7 x 4) + (3 x 5) + (9 x 2) = 109

17. Answer 1: ( 6 x 8)+ (7 x 4) + (3 x 5) + (9 x 2) = 109 is this it

18. (6 x 8)+ (7 x 8)+ (3+5)+ (9 x 2) = 109

19. (9 x 7) + (8 x 5) + (6 x 1) + (0 x 2) = 109

20. 7×2=14
3×6=18
4×8=32
9×5=45
90+10=100+9=109

21. (9×8)+(7+5)+(2×1)+(0x6)=109

22. (4×8)+(7×2)+(3×6)+(9×5)=109
