Answer:
28.5^2
Step-by-step explanation:
The formula is, b(base)+c(height)= b+c over 2. b+c/2.
B=19ft in this problem.
C=38ft
Knowing this, we can further simplify.
19+38/2
Now, we add 19 and 38.
(57)
57/2= 28.5
So, the anwser is 28.5^2
11 if you multiply 11 by both the number and and the variable you’ll get 11x-55=66. Add 55 to each side which will give you 121 then divide that by 11

Answer:
2x + 4 = 10 = x =3
Step-by-step explanation:
09 - 31 = 0 (the variable x is not present in the given system)
0 +5=6 (the variable x is not present in the given system)
2x + 4 = 10 = x = 3
09-1=4 (the variable x is not present in the given system)
51 - 7 = 1 (the variable x is not present in the given system)
3x + 1 = 9 = x = 8/3
