Answer:

Supplementary

Step-by-step explanation:

If you add the angles from A and B, they make a straight line, or 180 degrees. This angle relationship is called supplementary.

Solving the equation 2x^2-12x+6=0 using completing square method we get (x+3)^2=6

So, Option A is correct.

Step-by-step explanation:

We need to solve the equation 2x^2-12x+6=0 using completing square method.

Solving using completing square method

2x^2-12x+6=0

For completing the square we need to make formula a^2-2ab+b^2=(a-b)^2

Divide the equations by 2

x^2-6x+3=0

x^2-6x+3=0

Adding and subtracting (3)^2 on both sides.

(x)^2-2(x)(3)+(3)^2-9+3=0

(x+3)^2-6=0

(x+3)^2=6

Solving the equation 2x^2-12x+6=0 using completing square method we get (x+3)^2=6

So, Option A is correct.

  • Left to Right

<u>Geometry</u>

  • [Right Triangles Only] tan∅ = opposite over adjacent

Step-by-step explanation:

<u>Step 1: Define</u>

We are given a right triangle. We can use trig to find the missing side length.

<u>Step 2: Identify Variables</u>

<em>POV from the angle measure</em>

Angle = 23°

Opposite Leg = 25

Adjacent Leg = <em>x</em>

<em />

<u>Step 3: Solve for </u><em><u>x</u></em>

  1. Substitution [tangent]:                    tan23° = 25/x
  2. Multiply <em>x</em> on both sides:                xtan23° = 25
  3. Isolate <em>x</em>:                                          x = 25/tan23°
  4. Evaluate:                                          x = 58.8963
  5. Round:                                             x ≈ 58.9

Are 5x and x+5 equivalent expressions?
valkas [14]
No,

5x means 5 is being multiplied by a number (x)

x+5 means that’s a number (x) is being added to 5

Hope this helps ;)
