The area of this figure is 81m^2.
Answer:
the answer for the problem is 9
Step-by-step explanation:
35-26=9
it’s a statistical question
Answer:
84 is the highest possible course average
Step-by-step explanation:
Total number of examinations = 5
Average = sum of scores in each examination/total number of examinations
Let the score for the last examination be x.
Average = (66+78+94+83+x)/5 = y
5y = 321+x
x = 5y -321
If y = 6, x = 5×6 -321 =-291.the student cannot score -291
If y = 80, x = 5×80 -321 =79.he can still score higher
If If y = 84, x = 5×84 -321 =99.This would be the highest possible course average after the last examination.
If y= 100
The average cannot be 100 as student cannot score 179(maximum score is 100)
Answer:
13. 4(x+3) 15. 5(x+7) 17. cannot be factored 19. 3(2x-3) 21. 9(8-2x)
23. 50(2x + 3) 25.4(x+9)
Step-by-step explanation:
Hope this helps
