Answer:
x²^2 + 4x + 4 - 9y²=(x+2-3y) (x+2-3y)
Step-by-step explanation:
hello :
x²+4x+4 = x²+2(2x)+2²=(x+2)² use identity : (a+b)² = a²+2ab+b²
( x² + 4x + 4) - 9y² = (x+2)²-(3y)² = (x+2-3y) (x+2-3y) use identity :
a²-b² =(a-b)(a+b)
Answer:
B
2(6)+4 > 16 x > 6 2(7) + 4 > 16
12+4=16 14+4>16 18>16
Answer: 8
Step-by-step explanation: do 40 divided by 5 and get 8
8 foot=96 inches
96=6x
96/6= 6/6
