Use factoring to solve 3x^2-11x-6=0

Mathematics
1 answer:
Zielflug [23.3K]3 years ago
4 0

Answer:

x = -0.62 and x = 4.29

These values are approximations !

Step-by-step explanation:

You can not use Factoring to solve this equation. Perhaps you did not use the exact notation as in the original question?

Anyway, to solve it, you can still use the ABC formula.

3x²-11x-6=0

a = 3

b =-11

c = -6

x = [11 + √{121 -4(3 *-6)} ]/ 2*3

x = [11 + √{121 -4(-24)} ]/ 6

x = [11 + √{121 + 96} ]/ 6

x = [11 + √{217} ]/ 6

x = 4.29 This is an approximation !

x = [11 - √{121 -4(3 *-6)} ]/ 2*3

x = [11 - √{121 -4(-24)} ]/ 6

x = [11 - √{121 + 96} ]/ 6

x = [11 - √{217} ]/ 6

x = -0.62 This is an approximation !

B = 10 feet area = 35 feet 2 Find the height of the triangle.
Alexandra [31]

Answer:

Height is 7m

Step-by-step explanation:

B = 10 feet area = 35 feet 2 Find the height of the triangle.

Area of triangle = 1/2 b×h

35 = 1/2(10×h)

35 × 2 = 10h

70 = 10h

h = 70/10

h = 7m

Choose all of the transformations that would change a triangle into one that is similar, but not congruent. Which transformation
Vsevolod [243]

You didn't supply a list.  The so-called rigid transformations of translation, rotation and reflection create congruent triangles.

Generally it's dilation by a factor about a point is preserves similarity but not congruency.  Any transformation which includes such scalings but is otherwise rigid also preserves similarity but not congruency.

Nikitich [7]

---------------------------------------︵‿︵‿୨♡୧‿︵‿︵--------------------------------------

Answer:

765 grams

Step-by-step explanation:

Exchange:

2.33 kg = 2330 gr

Grams of grapes that are left after giving 800 grams to her brother:

2330 - 800 = 1530 gr

Grams of grapes each sister will get if Doreen shares the remaining equally:

1530 : 2 = 765 gr
