We will determine the surface area as follows:
So, the total surface area is 150 cm^2.
24=N is the correct answer
Answer:
x = 2
Step-by-step explanation:
log27(x + 7) - log27(x - 1) = ⅔
log27[(x + 7)/(x - 1)] = ⅔
(x + 7)/(x - 1) = 27^⅔
(x + 7)/(x - 1) = 9
x + 7 = 9(x - 1)
x + 7 = 9x - 9
8x = 16
x = 2
