Answer:
don't go to college depends on what you want to do they will teach you how to do it and still get paid
The value of the expression is 79
Let's solve for x using trigonometric relation ( Cos )
we know,
now
hence, the value of x is 
2x^2-12x+18=0
Factor out GCF
2(x^2-6x+9)
Factor trinomial
(x-3)(x-3)
Proof
-3-3=-6
-3^2=9
Zeros
x-3=0
x=3
Final answer: B
Answer:
C - 21:28
Step-by-step explanation:
this is solved by a little bit of trial and error. divide the possible answer numerators by 15, and check if it's the same for the denominator.
For C I did this:
Divided the denominators: 28 ÷ 20 = 1.4....so that's 1.4.
Let's test it out for the numerator now. 21 ÷ 15 = 1.4.
So there's your answer.
