The answer would be A because if you combine all the like terms you will get A as a result.

-2x^2+8x-9+4x+7x^2+2
-2x^2+7x^2 combine both of these and it will get you 5x^2
And then you would do 8x+4x which would be 12x and lastly you would -9+2 which would be -7 so the answer is A.

Hope this helps!!

pishuonlain [190]

Answer:

f(- 2) = 3(- 2)² + 2(- 2) - 1 = 3(4) - 4 - 1 = 12 - 5 = 7 , then

g(7) = 4(7) - 5 = 28 - 5 = 23

Cosine = Adjacent / Hypotenuse

Tangent = Opposite / Adjacent

sin B = opposite / hypotenuse

The side opposite of angle B is side b.  The hypotenuse is c.

sin B = b / c
