Answer:
The coefficient is 9
Step-by-step explanation:
(a)(b)(c)+(a)(2c)(2a)+(2b)(b)(c)+(2b)(2c)(2a)
abc+4ca^2+2cb^2+8abc
9abc+4ca^2+2cb^2
Answer: Hello mate!
We have the equation 2x^2 + x = 14
let's solve it for x:
2x^2 + x - 14 = 0
the solutions can be obtained with the equation:
then the solutions are:
(-1 - 10.63)/4 = -2.907, that rounded to the hundreths is equal to -2.91 (because the number after the hundredth place is a 7, so we round up)
and
(-1 +10.63)/4 = 2.407, that when rounded to the hundreths place is equal to 2.41 (the same reason as before)
then the answers are -2.91 and 2.41
This is a notable trinomial.
You have to find two number which summed give 5 and multiplied give 6
In this case 2 and 3
2+3 = 5 and 2*3 = 6
So (y+2)(y+3)
This is the concept of trigonometry, the sine, cosine and tangent of 11/6 pi radians will be as follows;
11/6pi=11/6*180=330
thus;
tan 330=-0.5774
sin 330=-0.5
cos 330=-0.8660
