16 because 3 divided by 8 is 0.375 and 6 divided by 0.375 is 16.
Answer:
16y + 32
Step-by-step explanation:
Expand each term.
(y+6)² - (y-2)²
= (y+6)(y+6) - (y-2)(y-2)
= y² + 12y + 36 - (y² - 4y + 4)
Subtract the second group by changing each term's signs
= y² + 12y + 36 - y² + 4y - 4
Collect like terms
= 16y + 32
is the answer.
This is because the slop is found by the difference of ys over the difference of xs.
