Answers

Answer 1

Answer: $3\cdot √(18)=3\cdot √(9\cdot 2)=3\cdot √(9 )\cdot √(2)=3\cdot 3\cdot √(2)=9√(2)$

Answer 2

Answer: The square root of 18 = 4.24264068712. Rounding it would just be 4.2. Then 3 times 4.2 is 12.6

Solve this inequality: 3p – 16 < 20. A. p < 1/3
B. p < 11/3
C. p < 12
D. p < –12

Answers

If you would like to solve the inequality 3 * p - 16 < 20, you can calculate this using the following steps:

3 * p - 16 < 20
3 * p < 20 + 16
3 * p < 36 /3
p < 36/3
p < 12

The correct result would be C. p < 12.

The solution to the inequality is p < 12.

Option C is the correct answer.

We have,

To solve the inequality 3p - 16 < 20, you can follow these steps:

- Add 16 to both sides of the inequality:

3p - 16 + 16 < 20 + 16

3p < 36

- Divide both sides of the inequality by 3

(since the coefficient of p is 3 and we want to isolate p):

(3p)/3 < 36/3

p < 12

Thus,
