Step-by-step explanation:

4n - 12 < 2n + 2 is for n=6

4×6 -12 < 2×6 +2

24 - 12 < 12 + 2

12 < 14 correct

for n=7

4×7 - 12 < 2×7 + 2

16 < 16 incorrect

for n=8

4×8 - 12 < 2×8 + 2

20 < 18 incorrect

for n=9

pantera1 [17]

Answer:

6x^2

Step-by-step explanation:

Express as product of prime factors.

30x^2=2\times 3\times 5\times x^2

66x^5=2\times 3\times 11\times x^5

The greatest common factor is the product of the least powers of the common factors.

The GCF is
