The answer is 2x+6
Explanation: 2 times 3 is 6 and 2 times x is 2x
If you know the formular a^3+b^3=(a+b)(a^2-ab+b^2), you can solve this problem.
8 is 2 cubed, so x^3+2^3=(x+2)(x^2-2x+4)
so the other quadratic factor is x^2-2x+4
ANSWER:
Positive Correlation
EXPLANATION:
4 + 3x = 12
3x = 12 - 4
3x = 8
x = 8/3
x = 2,6 grams
x^2b + t = x^2e
x^2e - x^2b = t
x^2(e - b) = t
x^2 = t /(e -b)
x = √[t /(e -b)] or x = - √[t /(e -b)]
