Answer:

n  =  3 , − 6

Step-by-step explanation:

n ^2 + 3 n − 12 = 6 .

Subtract  6  from both sides.

n ^2 + 3 n − 12 − 6 = 6 −6

n^ 2 + 3 n − 18 = 0

⇒ ( n + 6 ) ( n − 3 ) = 0

∴ n =  − 6 , 3

For question 1:
1% = 120 ÷ 100 = 1.2
15% = 1.2 × 15 = 18
So, 15% of 120 is 18

For question 2:
68.4 ÷ 72 = 0.95
0.95 × 100 = 95%
So, the percentage is 95%

For question 3,
1% = 12.5 ÷ 8 = 1.5625
100% = 1.5625 × 100 = 156.25
So, 8% of 12.5 is 156.25.

For question 4,
1% = 48 ÷ 40 = 1.2
100% = 1.2 × 100 = 120
So, 40% of 48 is 120.

For question 5,
1% = 195 ÷ 100 = 1.95
62.5% = 1.95 × 62.5 = 121.875
So, 62.5% of 195 is 121.875
