Answer:
f(3) = 68
Step-by-step explanation:
→ f(1) = 2 ⇒ f(2) = f²(2 − 1) + 4
= f²(1) + 4
= 2² + 4
= 8
………………………………………………
→ f(2) = 8 ⇒ f(3) = f²(3 − 1) + 4
= f²(2) + 4
= 8² + 4
= 64 + 4
= 68
Answer:
2139m (total area)
Step-by-step explanation:
I am like 98% sure this is right
23* 31= 713 (1 side area)
713+713=1426 (2 sides area)
31-12=19 (middle height)
19*23= 437 (middle area)
437+1426=2139m (total area)
His final answer would be A. 0.0045
Umm. i am not sure if this will help but, i would pick the first one. mainly because, i like to think of it as money, like for example. If i had two separate banks, and in both of them i had seven dollars. If i give seven dollars to a charity and there is nothing left in my bank, i would add my other money from my second bank into my first one. that way i will have money in the bank i would normally go to.
