It is option C.look:

If f(x)=2x^2-5 and g(x)=x^2-4x-8, find (f-g)(x)

Marianna [84]

(f-g)(x) is equivalent to f(x) - g(x)

So that would be (2x²-5) - (x²-4x-8) = 2x² - x² + 4x + 8 - 5 = x² + 4x + 3

Hope this helps.

Need help solving the equation, trying to figure whether I multiply or divide.

USPshnik [31]

Answer:

m∠B = 43°

b = 26.1

c = 38.3

Step-by-step explanation:

By applying triangle sum in the given triangle,

47° + 90° + m∠B = 180°

137° + m∠B = 180°

m∠B = 43°

By applying sine ratio to the angle measuring 47°.

sin(47°) = $\frac{\text{Opposite side}}{\text{Hypotenuse}}$

= $\frac{28}{c}$

c = $\frac{28}{\text{sin}(47^{\circ})}$

c = 38.28

c ≈ 38.3

By applying cosine rule,

cos(47°) = $\frac{\text{Adjacent side}}{\text{Hypotenuse}}$

= $\frac{b}{c}$

= $\frac{b}{38.3}$

b = 38.3[cos(47°)]

b = 26.1
