Answer:

the answer is 16

Step-by-step explanation:

We already know that n = 3, so let's put 3 instead of n:

6(3) - 2

Then, we need to get rid of the parenthesis:

6 * 3 = 18

We got 18 - 2.

Finally, we simplify:

18 - 2 = 16

And we're done!

Solve the inequality 3x - 5 < 4.
Pachacha [2.7K]

Answer:

      x < 3

Step-by-step explanation:

Since 3x - 5 < 4 then we can transpose the inequality to make x the subject of the equation:

    If 3x - 5 < 4

⇒    3x < 4 + 5

⇒       x < 9 ÷ 3

⇒       x < 3

What number should be added to both sides of the equation to complete the square? x2 – 6x = 5
choli [55]

Answer: Add 9 to both sides to complete the square

Step-by-step explanation:

The formula for the number you need to add to complete the square is (b/2)^2. In this case, b = -6, so:

(b/2)^2 = (-6/2)^2 = (-3)^2 = 9.

(After adding 9 to both sides, you will get x^2 - 6x + 9 = 14 which can be factored to (x - 3)^2 = 14)

Please help me, will mark you as brainiest! Don’t answer if you don’t know it!
Vesnalui [34]

Answer:

The correct option is;

26.8

Step-by-step explanation:

The given parameters are;

The perpendicular bisectors of the sides of ΔMNP = Segments OQ, OR, and OS

Therefore;

in Segment MN, segment QM = segment QN, by definition of bisected line

Segment OQ = Segment OQ by reflexive property

∠OQM = ∠OQN = 90° by definition of perpendicular bisector

∴ ΔOQN ≅ ΔOQM, by SAS rule of congruency

Segment MO ≅ Segment ON by Congruent Parts of Congruent Triangle are Congruent, CPCTC

Segment MO = Segment ON = 26.8, by definition of congruency

Segment MO = 26.8
