Answer:
Step-by-step explanation:
Factor out 6
I assume you mean 6x^2+30x+36, because that makes far more sense
6(x^2+5x+6) = 6(x^2 + 2x +3x +6)
(To find that it is 2x and 3x: 2 +3 = 5, 2 * 3 = 6)
Factor by grouping:
6* x(x+2) +3(x+2) = 6(x+3)(x+2)
For binomials, it could be either (6x+18) (x+2) or (x+3) (6x+12), depending on where you multiply the 6.
n+6=6nStep-by-step explanation:
Enter them into a calculator (most significant digit first), pressing the "+" key between them and the "=" key after the last one.
The cosine of 30° is √3 / 2.
Since cosine is Adjacent over Hypotenuse, Hypotenuse = (2 / √3) * 9 = 18 / √3.
The cosine of 45° is √2 / 2.
Therefore, X = (2 / √2) * (18 / √3) = 36 / √6 = 18 / √1.5 = C
