Answer:

The answer to your question is the letter C

Step-by-step explanation:

Data

When we multiply a scalar by a matrix, we must multiply the scalar by each of the numbers of the matrix and the result of the multiplication stays in the same place.

For this problem:

                             3  | -2  0 |   =    | (-2 x 3)     (0 x 3) |

                                 |  4 -7  |         | (4 x 3)      (-7 x 3) |

                                               =    | -6     0 |

                                                      | 12   -21 |

Joel built a model town. He constructed three buildings that each had a volume of 18 cm cubed. Each building looked different. W
morpeh [17]

Answer:

The three buildings can look like following:

1. The building can look like a cube, with each side and height equal to 2.62 cm.

2. The building can look like a cuboid, with 3 cm length, 1 cm breadth and 6 cm height.

3. The building can look like a pyramid, with 3 cm length, 3 cm breadth and 6 cm height.

Step-by-step explanation:

The three possibilities of the appearance or shape of the building, with the volume equal to 18 cm³ are as follows:

1. CUBIC SHAPE:

The building can look like a cube with the length of each side and height given as:

Volume of Cube = 18 cm³ = L³

L = ∛18 cm³ = 2.62 cm

<u>Thus, the building can look like a cube, with each side and height equal to 2.62 cm.</u>

<u></u>

2. CUBOID SHAPE:

The building can also look like cuboid with the following dimensions.

Length = 3 cm

Breadth = 1 cm

Height = 6 cm

Thus, the volume becomes:

Volume of Cuboid = Length * Breadth * Height

Volume of Cuboid = 3 cm * 1 cm * 6 cm = 18 cm³

<u>Thus, the building can look like a cuboid, with 3 cm length, 1 cm breadth and 6 cm height.</u>

<u></u>

3. PYRAMID SHAPE:

The building can also look like pyramid with the following dimensions.

Length = 3 cm

Breadth = 3 cm

Height = 6 cm

Thus, the volume becomes:

Volume of Pyramid = (Length * Breadth * Height)/3

Volume of Cuboid = (3 cm * 3 cm * 6 cm)/3 = 18 cm³

<u>Thus, the building can look like a pyramid, with 3 cm length, 3 cm breadth and 6 cm height.</u>

Correct answer is A.

(x^2+4x-3)(2x^2+x+6)&#10;\\=x^2(2x^2+x+6)+4x(2x^2+x+6)-3(2x^2+x+6)&#10;\\=2x^4+x^3+6x^2+8x^3+4x^2+24x-6x^2-3x-18&#10;\\=2x^4+x^3+8x^3+6x^2+4x^2-6x^2+24x-3x-18&#10;\\=2x^4+9x^3+4x^2+21x-18
