Answer:
Center = (5,-3) radius = sqrt (36) = 6
Step-by-step explanation:
Since 4 = $3.88
Then 1 = 3.88/4
= $ 0.97
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
