3. 7

4. 13

5. 25

6. 40

7. 63

8. 23

9. 39

10. 84

12 is composite

10 is composite

7 is prime

13 is prime

25 is composite

40 is composite

63 is composite

23 is prime

39 is composite

84 is composite

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
