6 0

Answer:

 -a2 • (2a - b - 3c)

Step-by-step explanation:

Equation at the end of step  1  :

 ((4ab - 23a2) + 12ac)

 ————————————————————— • a

           4          

Step  2  :

           -8a2 + 4ab + 12ac

Simplify   —————————————————

                   4        

Step  3  :

Pulling out like terms :

3.1     Pull out like factors :

  -8a2 + 4ab + 12ac  =   -4a • (2a - b - 3c)  

Equation at the end of step  3  :

 -a • (2a - b - 3c) • a

Step  4  :

Multiplying exponential expressions :

4.1    a1 multiplied by a1 = a(1 + 1) = a2

Final result :

 -a2 • (2a - b - 3c)

What is the expression in factored form?
san4es73 [151]

Answer:  (4x + 3) (x + 2)

Step-by-step explanation:

We can rewrite 4x² + 11x + 6 as 4x² + 8x + 3x + 6

Since 4x² + 11x + 6  = 4x² + 8x + 3x + 6

                                = (4x + 3) (x + 2)

HELP MEEEEE<br> In complete sentences, describe the characteristics of this scatterplot.
Umnica [9.8K]

Step-by-step explanation:

Scatter plots are dots scattered all over the graph.  I think that this is the easiest graph because all you need to do is put a dot where you want it.

A scatter plot doesn't need any lines, all it needs is dots.

The side of one square is equal to 3m and its diagonal is equal to the side of a second square. Find the diagonal of the second
navik [9.2K]

Answer:

6m

Step-by-step explanation:

the side of first square = 3 m

area of first square = 3^2= 9 m^2

let the side of second square = x m

since diagonal of first square = x m as per the question

in a square each angle is 90 degree

therefore by applying pythagorus theorem ,

diagonal ^2 = side^2 + side ^2

diagonal^2 = 3^2+3^2=9+9

DIAGONAL= square root of 18

diagonal= 3\sqrt{2} m = side of second square

therefore in second square ,

one angle is 90  degree , therefore by applying pythagorue theorem

diaqonal^2 = side ^2 + side ^2 = (3\sqrt{2})^2 + ( 3\sqrt{2})^2

diagonal ^2 = 18 + 18

diagonal = square root of 36

therefore diagonal of second square is 6m

hope it helps you... please mark me as the brainliest..
