Answer:
18.4 km^2
Step-by-step explanation:
Surface area of a square pyramid = A=a²+2a√ h²
a = side length
h = slant height
3² + 2(3) x√ (9/4) x 3²
The answer for this question that needs an answer is n = 5
because 18(n-1) = 9(n+7) implies that 18n - 18 = 9n + 63 which implies that n =5 for the equation to hold true.
Answer:
y=4x+.0004
Step-by-step explanation:
y=4(x+1)^-4
