Answer:

we have 2 real solutions

Step-by-step explanation:

ax^2 + bx+c

discriminant

b^2-4ac

6x=-2x^2-3

subtract 6x from each side

0 = -2x^2 -6x-3

a= -2

b=-6

c=-3

b^2-4ac = (-6)^2 - 4(-2) (-3)

                36 - 24

                   12



if > 0 2 real solutions

= 0    1 real solution

 < 0 2 complex solution


since 12 > 0 we have 2 real solutions

I NEED HELP!!! ASAP!!!
omeli [17]

Answer:

A.

Step-by-step explanation:

In the picture, the estimated slope goes down, so it has to be negative, eliminating 2, B and D

It isn't a gradual line, as 6x is, so that is eliminated.

When we look at the estimated line, we can count out on the grid 3 to the right and 4 down, doing that a few times.  If you then connect the dots, it will be a line probably very close to your estimate.

bogdanovich [222]

<em>Answer:</em>

The exact form is 5/44 and decimal form is .1136

<em>Step-by-step explanation:</em>

Divide by a fraction and multiply by its reciprocal

5/8  * 2/11

Cancel the common factor 2

5/4  * 1/11

Multiply 5/4 and 1/11

<em>5/4(11)</em>

The result is

<em>5/44 or .1136</em>

This cuboid is made from cm squares
11Alexandr11 [23.1K]

Answer:

Step-by-step explanation:

Each signal unit cubes are 1 cm to each side

the dimensions of the large cube is 4 by 6 by 3      width height and depth

a) volume of the cube   Vol = area of the base times height  

              area of the base = the width times the depth  

              Volume = Base Depth

                            =  Width x Depth x Height

                            =      4 x 3 x 6

                            =       12 x 6

                Vol      =   72 cm ³

b )  the volume of the smaller cuboid has different dimensions    

             the smaller cube is 2 by 2 by 1      width height and depth

          Volume = Base Depth

                            =  Width x Depth x Heigh

                            =    2 x 2 x 1  

 Vol smaller cuboid    =   4

      How many smaller cubes can be made?

            The obvious answer might be to straight up divide the large cube volume by the smaler cuboid volume. That might work IF all of the cuboid dimensions divide evenly into the cube dimensions.

  Number of cuboid  =   Volume of the cube  /  Volume of the cuboid

                                  =             72 / 4

                                  =        18

Check this answer by dividing the dimension of the cube by the cuboid

         4 by 6 by 3

         2 by 2 by 1

      (4/2) by (6/2) by (3/1)

        2    by    3   by     3       = 2 x 3 x 3     =    18
