Answer:
X = 2, -8
Step-by-step explanation:
A. ( x + 3 )² = 25
2x² + 12x = 32
2(x² + 6x) = 32
x² + 6x + 9 = 16 + 9 [ addition of 9 from both sides ]
( x + 3 )² = 25
28
KARLEE HAS 4 PENCIL PACKS.
∴ 1 pack has 1/7 multiplied by X.
X/7 = 1, so X is 7.
AND THEREFORE 4 PACKS CONTAIN 7*4 = 28
16x > 12(2x - 6) - 24
16x > 24x - 72 - 24
16x > 24x - 96
-24x -24x
-8x > -96
x < 12
