X and 73 are same-side interior angles, which are supplementary (they add up to 180).
x + 73 = 180
x = 107
X and (6y - 79) are vertical angles, which are congruent (have the same measure/value.
x = 6y - 79
107 = 6y - 79
6y = 186
y = 31
Hope this helps!

Answer:
5 and 6
Step-by-step explanation:
16k^2 + 16k + 4
We can first start off by dividing every term by 4:
4 (4k^2 + 4k + 1)
to factor, you find which two number you can multiply with each other to get the middle term. So 2 and 2 to get 4. Substitute that into the equation
4 (4k^2 + 2k + 2k + 1)
the first two terms become a group and the last 2 terms become a group. Factor like terms out of the two groups.
4 (2k (2k + 1) + 1 (2k + 1))
4 (2k + 1)(2k + 1)
I think the answer would be 56. Bc the first job has 8 different people who could get the job and then once someone is chosen for that slot the next teaching position only has 7 candidates. So you would take 8*7 which equals 56.
