Which statement about the greatest common factor of 32n2 and 56n is true?
Lisa [10]

Answer:

It is 8n, because there is no greater term that is the factor of both 32n2 and 56n.

Step-by-step explanation:

The greatest common factor of the two expression is the term 8n.

It is the highest factor of both expressions that will divide them.

Given:

                32n²             56n

Factor them:

           2n(16n            28)

            4n(8n             14)

            8n(4n             7n)  - Beyond this, no common factor can divide them both.

Therefore 8n is the greatest common factor of the two.

If 0 < z ≤ 90 and sin(9z − 1) = cos(6z + 1), what is the value of z? z = 3 z = 4 z = 5 z = 6
iogann1982 [59]

Answer:

z = 6

Step-by-step explanation:

sin (9z - 1) = cos (6z + 1)

90 - (9z - 1) = 6z + 1

90 - 9z + 1 = 6z + 1

9z + 6z = 90

15z = 90

z = 6
