Answer:
D 180 in²
Step-by-step explanation:
step 1
2 (l) (w) + 2 (l) (h) + 2(h) (w)
step 2
2×(6)×(3) + 2×(6)×(8) + 2×(8)×(3)
step 3
2×(18) + 2×(48) + 2×(24)
step4
36 + 96 + 48 = 180 in²
Recall that cosine is the reciprocal of secant, so is the same fraction, just upside-down.
I think it would go like this:[40- 2 (8+2)]=10 I think
Here, just substitute the value of n = 7
an = -6(n-1)
an = -6(7-1)
an = -6(6)
an = -36
In short, Your Final Answer would be -36
Hope this helps!
