Answer:
Choice C. sin 105 = sin(60 + 45) = sin 60 cos 45 + cos 45 sin 60
Step-by-step explanation:
sin(A + B) = sin A cos B + cos A sin B
sin(105) = sin(60 + 45) = sin 60 cos 45 + cos 45 sin 60
Answer: choice C
2x^2+6x-8 the factors j and k will be the two values that satisfy two conditions...
jk=ac=-16 and j+k=b=6 so j and k must be 8 and -2
2x^2-2x+8x-8
2x(x-1)+8(x-1)
(2x+8)(x-1)
2(x+4)(x-1)
