Answer:
See below.
Step-by-step explanation:
1.
2a + 3 * (1 + 2) = 2a + 9: Yes. Expression is equivalent.
2.
33v = (3 * v) * 11: Yes. Expression is equivalent.
3.
3b - 19 + 2b = 3b + 19 - 2b: No. Both expressions are different answers.
4.
4(3c - 4) = 2(6c - 8): No. expressions are not equivalent.
The answer is 1.5 kilometers per minute
6.25 for each kids ticket and 11.75 for each adult ticket
The required relength is half of the length of AC
AC = sqrt(8 - (-2))^2 = 8 + 2 = 10
Therefore, the required length is 5.
Double every year
year one
4 times 2
year 2
4 times 2 times 2 aka 4 times 2^2
year 3
4 times 2 times 2 times 2 aka 4 times 2^3
obviously
at year 'n' the number of rabbits will be
4 times 2^n
