Factorise 6x^2 + 11x + 4​

Mathematics

MatroZZZ [7]3 years ago

Answer:

Step-by-step explanation:

6x^2+11x +4

Multiply the constant 4 by 6x^2.

Hence 4 times 6x^2 = 24x^2

Get two numbers when you multiply them it will give you 24 but if you add them it will give 11.

The numbers are +8 and +3 because +8 x +3= +24

and +8 + 3 = 11.

Substituting +8x +3x as 11x in the equation:

6x^2 +8x +3x +4

(6x^2+ 8x) + (3x + 4)

Factorizing the common things in the bracket.

2x(3x + 4) +1 (3x +4) since the common factor between (3x + 4) is 1.

Grouping the values outside together: (2x+1) (3x +4) =0

Therefore, 2x + 1 = 0 or 3x +4 = 0

2x = -1 or 3x = -4

x = -1/2 or -4/3.

Thanks.

(3x+4)(2x+1)

If the question asks you to find roots/solutions:

3x + 4 = 0
3x = -4
x = -1.33333333

2x + 1 = 0
2x = -1
x = -0.5

Which points can be connected to draw a line of symmetry through this diamond?
Makovka662 [10]

The line is drawn at point A and Point C is a line of symmetry because lines of symmetry make exactly two halves with similar shapes and sizes.

<h3>What is a line of symmetry?</h3>

It is defined as the line which will make exactly two halves with similar shape and size in geometry. For a two-dimensional shape, there is a line of symmetry, and for three-dimensional shapes, there is a plane of symmetry. In other words, if we make a mirror image of the shape around the line of symmetry, we will get exactly the same half portion.

We have given a figure in the picture.

The figure is a quadrilateral(a kite)

As we know, lines of symmetry make exactly two halves with similar shapes and sizes.

IF we draw a line from Point A to Point C we will get two similar and figures in size and shape.

Thus, the line is drawn point A and Point C is a line of symmetry because lines of symmetry make exactly two halves with similar shapes and sizes.

Last year, the mean running time for a certain type of light bulb was 8.5 hours. This year, the manufacturer has introduced a ch
Free_Kalibri [48]

Answer:

H0 : μ = 8.5

H1 : μ > 8.5

1 sample t test ;

Test statistic = 2.53

Pvalue = 0.994

No, we fail to reject the Null ;

There is no significant evidence to support the Claim that the mean running time of light bulb is greater Tha last year.

Step-by-step explanation:

H0 : μ = 8.5

H1 : μ > 8.5

Test statistic :

(xbar - μ) ÷ (s/sqrt(n))

(8.7 - 8.5) ÷ (0.5 / sqrt40)

Test statistic = 2.53

The Pvalue :

P(Z < 2.53) = 0.9943

Pvalue = 0.994

Decison region :

Reject H0 ; if Pvalue < α

0.9943 > 0.05 ; We fail to reject the Null

Match the labeled points on the graph to statements about their coordinates Two numbers with a sum of 2
Kamila [148]

Answer:

see explanation!

Step-by-step explanation:

Line N

  • A set of points where the coordinates of each point have a sum of 2

Line M

  • A set of points where the y-coordinates of each point is 10 less than its x-coordinate

Any coordinate on N has a sum of 2.

Any coordinate on M has a y that is 10 less than the x.
