Answer:

11. a) P = 27t³/8

    b) 27

    c) t = \sqrt[3]{\frac{64}{81} }

12. a) V = 2x³

    c) A = 10x²

Step-by-step explanation:

P = a * t³

1 = a * (2/3)³

a = 27/8

P = 27t³/8

--------

P = 27(2)³/8 = 27

--------

8/3 = 27t³/8

t = \sqrt[3]{\frac{64}{81} }

--------

V = x * x * 2x = 2x³

--------

A = 2(x * x) + 2(x * 2x) + 2(x * 2x) = 2x² + 4x² + 4x² = 10x²

1+4=5<br> 2+5=12<br> 3+6=21<br> 8+11=?

Oh, I SEE what da pattern is! =D
You see, like in this problem:
2 + 5 = 12
They did 5 times 2 = 10, plus da 2 in da problem = 12.
Same with 3 + 6 = 21, 6 times 3 = 18, 18 plus da 3 given in da problem = 21.
Just like 1 + 4 = 5, 4 times 1 = 4, plus da 1 in da problem = 5.
SO,
with that strategy, 8 +11 = 96, because 8 times 11 = 88, plus da 8 given in da problem = 96.
I hope I helped! =D
