Step-by-step explanation:
we know that
The surface area of the composite figure is equal to the area of all its square faces
Each face area is one square unit
so

Answer:
x = 21
Step-by-step explanation:
3x - 71 = 2x - 50
3x - 2x = -50 + 71
x = 21
Check:
3(21) - 71 = 2(21) - 50
63 - 71 = 42 - 50
-8 = -8

The answer is the third one need any more help let me know
Answer:
1/3
Step-by-step explanation:
To change from one base to another, we use the formula
Logb x = Loga x/Loga b
log1/9 (3^(1/3) /3)
log3 ((3^(1/3) /3))
-------------------------
log3 (1/9)
Log a /b = log a - log b
and 1/9 = 3^-2
log3 ((3^(1/3) ) - log3 (3)
-------------------------
log3 (3^-2)
log a^b = blog a
1/3 log3 (3 ) - log3 (3)
-------------------------
-2log3 (3)
We know log3 (3) =1
1/3 (1) - 1
-------------------------
-2 (1)
1/3 - 1
-------------------------
-2
-2/3

-2
Copy dot flip
-2/3 * -1/2
1/3
