Answer:

  • y = (x + 6)² - 9

Step-by-step explanation:

y = x² + 12x + 27

  = x² + 2*6*x + 6² - 6² + 27

  = (x + 6)² - 36 + 27

  = (x + 6)² - 9

Correct choice is A

N76 [4]
X + y = 38
2x + 5y = 100
Where x is how many 2 pointers there were on the test and y how many 5 pinters there were

Elimination method:
2x + 2y = 76
2x + 5y = 100

2x - 2x + 2y - 5y = 76 - 100
-3y = - 24
y = 8
Apply it to the equation to get x
x + 8 = 38
x = 30
30 two pointers
8 five pointers
