Su is the only child under 12 years of age, therefore, she is only child entering for free.
That is 2015! or 2015 factorial
that is big
not sure if a joke but the answer is (see attachment)
or about 1.15369522906899370...*10⁵⁷⁸⁶ in scientific notation
The the first one the answer should be -4
For the second one the answer should be 3
X = -6y - 12
4x + 5y =-39
4x + 5y = -39
-4(-6y - 12) + 5y = -39
-4(-6y) + 4(12) + 5y = -39
24y + 48 + 5y = -39
29y + 48 = -39
29y = -87
y = -3
x = -6y - 12
x = -6(-3) - 12
x = 28 - 12
x = 6
(x, y) = (6, -3)
Answer:The prime factorization is the product of the circled primes. So the
prime factorization of 24 is 24 = 2 · 2 · 2 · 3 = 3.
