When asked to rewrite the expression (x3 + 2x? – x)-(-x3 + 2x2 + 6), Denise made a mistake. She did not get the correct answer,

DanielleElmas [232]

Answer:

She rewrote the problem without parentheses: x3+ 2x2 - x + x3 – 2x2 +6

Step-by-step explanation:

It looks like she didn't fully distribute the -

(x3 + 2x2 - x)-(-x3 + 2x2 + 6) :Original

x3+ 2x2 - x + x3 – 2x2 +6 :Changed

(x3 + 2x2 - x)-(-x3 + 2x2 + 6)

x3 + 2x2 - x + x3 - 2x2 - 6

x3 + x3 + 2x2 - 2x2 -x - 6

PLEASE HELP ASAP<br> TRIGONOMETRY

valentinak56 [21]

Answer:

9). x = 36.9°

10). x = 18.3°

Step-by-step explanation:

9). By applying tangent rule in the given triangle,

tan(x) = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

tan(x) = $\frac{9}{12}$

x = $\text{tan}^{-1}(\frac{3}{4})$

x = 36.87°

x = 36.9°

10). By applying sine rule in the given triangle,

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

sin(x) = $\frac{11}{35}$

x = $\text{sin}^{-1}(\frac{11}{35})$

x = 18.32

x ≈ 18.3°
