Simplify:
Solution ===> −7 + 12 − 3(50 − 4(2 + 3)) =========> -85
= 5 − 3(50 − 4(2 + 3))
= 5 − 3(50 − (4)(5))
= 5 − 3(50 − 20)
= 5 − (3)(30)
= 5 − 90
= −85
Answer ================> -85
Simplify:
1/3 + 6(2/3 - 1/6)^2
1/3 + 6(1/2)^2
1/3 + 6(1/4)
1/3 + 3/2
Answer =======> 11/6 =========> Decimal =======> 1.833333.....
Hope that helps!!!! : )
well, the recursive rule of aₙ = aₙ₊₁ + 7, where a₁ = 15, is simply saying that
we start of at 15, and the next term is obtained by simply adding 7, and so on.
well, that's the recursive rule.
so then let's use that common difference and first term for the explicit rule.

I blieve answer is A........mmmmmmmmmmmm
You can use this formula to solve this problem... it uses the surface area to find the volume.
V= (A^3/2)/(6√pi)
Substitute the surface area value into "A" and then solve as you would on paper. I'm sorry I couldn't show you the entire process but this should get you your answer. Plus if your teacher asks for work, I just set you up and everything else should be self explanatory.
But the answer is ----> 33.5 inches cubed
