The equation that is quadratic form is 6(x + 2)²+ 8x + 2 + 1 = 0

<h3>What is a quadratic equation?</h3>

A quadratic equation is an algebraic expression whose polynomial is in the order of two. The general formula for representing a quadratic equation takes the order of:

  • ax² + bx + c = 0

From the given options, the equation that takes a quadratic form is:

6(x + 2)²+ 8x + 2 + 1 = 0

solve the brackets

6(x² + 4x + 4) + 8x + 3 = 0

6x² + 24x + 24 + 8x + 3 = 0

6x² + 32x + 27 = 0

If €1 is with £0.89, and £1.00 is worth ¥48, what is ¥256 in €?
anastassius [24]
I don't know where to find those number on my keyboard so I will subsitute
€=x£=y¥=zso
1x=0.89y
and 1y=48z

first find conversion factor from z to x

1x=0.89y
y=48z
subsitute 48z for y in first equation
x=0.89(48z)
x=42.72z
divide both sides by 42.72
x/42.72=z

256z is wanted so
multiply both sides by 256
x/1 times 256/42.72=256z
5.99251x=256z

there are aprox 5.99x in 256z or about 6

Can someone plz help me with 11,12,13 plz show work
dimaraw [331]

Answer:

  11.  x = -3+√37 ≈ 3.08276

  12.  x = 11.2

  13.  x = -6 +6√5 ≈ 7.41641

Step-by-step explanation:

In each case, the relation of interest is ...

  (distance to circle near) × (distance to circle far) = (distance to circle near) × (distance to circle far)

When there is only one point of intersection of the secant with the circle—because it is a tangent—then the product is the square of the length of the tangent.

11. 2(2+12) = x(x +6)

  x² +6x -28 = 0

  (x +3)² -37 = 0

  x = -3+√37 ≈ 3.08276

12. 5(5+x) = 9(9)

  5x +25 = 81

  x = 56/5 = 11.2

13. x(x +12) = 12(12)

  x² +12x -144 = 0

  (x +6)² -180 = 0

  x = -6 +√180 ≈ 7.41641

_____

<em>Comment on this secant rule</em>

This rule turns out to apply whether the point of intersection of the secant lines is outside the circle (as in these problems) or inside the circle (as in problem 9). The product of the two distances from the point of intersection to the circle is a constant for a given pair of intersecting secants/chords.
