<u>Answer(s):</u>
- Part-1: B and C
- Part-2: C and E
<u>Verification:</u>
<u>Part-1:</u>
Let's simplify the expression.
- => 4(w + 3) - 2
- => 4w + 12 - 2
- => 4w + 10
<u>We got the result, which is 4w + 10. Now, let's see which expressions are equal to 4w + 10.</u>
<u>Option A</u>
- 4w + 3 - 2 = 4w + 10
- => 3 - 2 = 10
- => 1 ≠ 10 (Incorrect)
<u>Option B</u>
- 4w + 12 - 2 = 4w + 10
- => 12 - 2 = 10
- => 10 = 10 (Correct)
<u>Option C</u>
- 4w + 10 = 4w + 10
- => 0 = 0 (Correct)
<u>Option D</u>
- 14w = 4w + 10
- => 10w ≠ 10 (Incorrect)
<u>Option E</u>
- 4w + 12 - 8 = 4w + 10
- => 12 - 8 = 10
- => 4 ≠ 10 (Incorrect)
<u>Option F</u>
- 4w + 4 = 4w + 10
- => 4 ≠ 10 (Incorrect)
Hence, <u>Option B and C are correct.</u>

<u>Part-2:</u>
Let's simplify the expression.
- 3(2n + 3) + 9
- => 6n + 9 + 9
- => 6n + 18
Now, let's verify all options to see which are correct.
<u>Option A</u>
- 15n + 9 = 6n + 18
- => 9n ≠ 9 (Incorrect)
<u>Option B</u>
- 6n + 3 + 9 = 6n + 18
- => 6n + 12 = 6n + 18
- => 12 ≠ 18 (Incorrect)
<u>Option C</u>
- 6n + 18 = 6n + 18
- => 0 = 0 (Correct)
<u>Option D</u>
- 6n + 6 + 9 = 6n + 18
- => 6n + 15 = 6n + 18
- => 15 ≠ 18 (Incorrect)
<u>Option E</u>
- 6n + 27 - 9 = 6n + 18
- => 6n + 18 = 6n + 18
- => 0 = 0 (Correct)
<u>Option F</u>
- 3(5n) + 9 = 6n + 18
- => 15n + 9 = 6n + 18
- => 9n ≠ 9 (Incorrect)
Hence, <u>the answers are Option C and E.</u>

Answer: y=kx/w^2
Step-by-step explanation:
y is directly proportional to x
y∝x
y=kx
y inversely proportional to the square of w.
y ∝ (1/(w)^2)
y=k/w^2
y=kx/w^2
