Answer: -\frac{2}{3x+1}

<u>Step-by-step explanation:</u>

\frac{-x-2}{9x^{2}-1} + \frac{-5x+4}{9x^{2}-1}

= \frac{-x-2-5x+4}{9x^{2}-1}

= \frac{-6x+2}{9x^{2}-1}

= \frac{-2(3x-1)}{(3x-1)(3x+1)}

In the diagram below, you are given that ∠AVD = ∠BVE = ∠CVF= 90° and ∠CVD = 22°. If ∠AVB= ∠EVF, how many degrees are in the meas
lana66690 [7]

Answer:

m∠AVF = 158°

Step-by-step explanation:

In the diagram attached,

m∠AVD = m∠BVE = m∠CVF = 90°

m∠CVD = 22°

∠AVB = ∠EVF

Since ∠AVD = ∠AVC + ∠CVD

Therefore, 90° = m∠AVC + 22°

m∠AVC = 90° - 22°

             = 68°

Similarly, m∠CVF = m∠CVD + m∠DVF

90° = 22° + m∠DVF

m∠DVF = 68°

m∠AVC = m∠DVF = 68°

Now ∠AVF = ∠AVD + ∠DVF

                  = 90° + 68°

                  = 158°
