Answer:

1/\sqrt{2} - 1/4

Step-by-step explanation:

We can write 2\sqrt{8} as 2*\sqrt{4}*\sqrt{2}

That becomes 4\sqrt{2}, since the square root of 4 is 2 (±2, to be exact)

(4/(4\sqrt{2})  - ( \sqrt{2}/4\sqrt{2})

1/\sqrt{2} - 1/4

Solve the inequality and write in interval notation <br><br> 2−5|6x−4|&lt;−13
lorasvet [3.4K]

The solution to the inequality is (7/6, ∝) and (-∝, 7/6)

<h3>How to solve the inequality?</h3>

The inequality expression is given as:

2−5|6x−4|<−13

Subtract 2 from both sides

|6x−4|<−15

Divide through by -5

|6x−4| > 3

Remove the inequality sign

6x - 4 > 3 or 6x - 4 < 3

Add 4 to both sides

6x > 7 or 6x < 7

Divide by 6

x > 7/6 or x < 7/6

In interval notation, we have:

(7/6, ∝) and (-∝, 7/6)

HELP HELP I DONT UNDERSTAND THIS
NemiM [27]

Answer:

1) angle bisector

2) w = 72°

3) t = 44°

4) t = 51°

5) FG = 16 units

Step-by-step explanation:

1) Given that, ∠VYW ≅ ∠WYV

The line which cuts any angle into equal halves is angular bisector of the angle

⇒ YW is angle bisector

2) In a triangle, sum of two interior angle is equal to exterior angle of other side.

⇒ w-41° + w-31° = w.

⇒ w = 72°

3) Sum of interior angles in a pentagon is 540°

(For a n sided it is (n-2)180° )

⇒ 149° + 139° + t+32° + 3t +t = 540°

⇒ t = 44°

4) sum of all exterior angles taken one at each vertex = 360°

⇒ 2t-50° + 46° + 2t + 34° + 2t-50° + 34° + 40° = 360°

⇒ t = 51°

5) Here, by comparing ΔHGF and ΔHIF

   ∠GHF = ∠IHF

  ∠HGF = ∠HIF

 and HF is common side for both triangles

⇒  ΔHGF ≡ ΔHIF ;  i.e) ΔHGF , ΔHIF are congruent triangles

⇒ FG = FI = 16 units
