Mathematics
1 answer:
Nataly_w [17]4 years ago
6 0

Answer: 16

Step-by-step explanation:

For a perfect square each factor is identical.

Now, we have to find a number that adds to get 8.

The only option is (x+4)(x+4). When you distribute, you get x²+8x+16.

Now, we know that the missing number is 16.

Led by vocalist Marlena McGhee Smalls, Gullah
sweet-ann [11.9K]

The correct option is (B) the Hallelujah Singers of South Carolina to help to preserve the Gullah tradition through songs and stories.

<h3>Who is a vocalist?</h3>
  • Another definition of a vocalist is a classically trained singer.
  • The emphasis in this definition of a vocalist is on technique and adherence to the composition.
  • A singer, on the other hand, is a vocal performer who attempts to convey the emotion of the composition through their voice.
  • The technique is less important.

To find the correct option:

  • The only correct construct here is (B) because the others imply that the tradition is only preserved through the efforts of the singers.

Therefore, the correct option is (B) the Hallelujah Singers of South Carolina to help to preserve the Gullah tradition through songs and stories.

7x² + 6x - 1<br> Algebra 3|factoring
GaryK [48]

Answer:

(7 x - 1) (x + 1)

Step-by-step explanation:

Factor the following:

7 x^2 + 6 x - 1

Factor the quadratic 7 x^2 + 6 x - 1. The coefficient of x^2 is 7 and the constant term is -1. The product of 7 and -1 is -7. The factors of -7 which sum to 6 are -1 and 7. So 7 x^2 + 6 x - 1 = 7 x^2 + 7 x - x - 1 = (7 x - 1) + x (7 x - 1):

(7 x - 1) + x (7 x - 1)

Factor 7 x - 1 from (7 x - 1) + x (7 x - 1):

Answer: (7 x - 1) (x + 1)

Find the following product if possible. Explain if it is not possible. <br><br> (See picture)
Nataly_w [17]

Answer:

The answer to your question is the letter a

Step-by-step explanation:

 |    1    4    -1   |      |  2    -1   |

 |    3   2    2   |      |  0     3  |         Product  = 2 x 3   and 3 x 2  = 2 x 2

                              | 5     2  |          It is possible to do this product,

                                                      the result will be a 2 x 2 matrix

Process

1.- Multiply first row by first column and second row by second column.

2.- Multiply the second row by the first column and second row by the second column.

  = (1 x 2) + (4 x 0) + (-1 x 5) = 2 + 0 - 5 = -3

  = (1 x -1) + (4 x 3) + (-1 x 2) = -1 + 12 - 2 = 9

  = (3 x 2) + (2 x 0) + (2 x 5) = 6 + 0 + 10 = 16

  = (3 x -1) + (2 x 3) + (2 x 2) = -3 + 6 + 4 = 7

Result

             |  3   9  |

             | 16   7  |
