Find the surface area of one side and multiply it by 6
Answer:
390 ft²
Step-by-step explanation:
25x10= 250
20x7= 140
250+140= 390
18 + 18h = 180, subtract 18 from 180, then divide by 18 and that should give you 9.
9 = h

Simplfiy 3 + 8 to 11.
Answer:
f(n) = -6n - 10.
Step-by-step explanation:
This is arithmetic sequence with first term a1 = -16 and common difference d = -6.
So f(n) = a1 + d(n - 1)
= -16 - 6(n - 1)
= -16 - 6n + 6
= -6n - 10.
Checking:
f(10) = -6(10) - 10 = -70.
