Answer 1

HERE IS YOUR ANSWER

the answer is 20


as 8^2 - 5^2 = 39

8^2 - 6^2 = 28

5^2 - 4^2 = 9


then the ? = 6^2 - 4^2 = 20

HOPE MY ANSWER IS CORRECT

Answer 2

Answer:

Step-by-step explanation:

Here,

5, 8, 39

→ 8² - 5² = 64 - 25 = 39

8, 6, 28

→ 8² - 6² = 64 - 36 = 28

5, 4, 9

→ 5² - 4² = 25 - 16 = 9

It means,

if a > b,

a, b, a² - b² is one set.

Therefore,

4, 6, ?

→ 6² - 4² = 36 - 16 = 20

Also,

a, b, (a + b)(a - b) is true.

5, 8, 39

→ (8 + 5)(8 - 5) = 13 × 3 = 39

8, 6, 28

→ (8 + 6)(8 - 6) = 14 × 2 = 28

5, 4, 9

→ (5 + 4)(5 - 4) = 9 × 1 = 9

Therefore,

4, 6, ?

→ (6 + 4)(6 - 4) = 10 × 2 = 20

∴ Answer is option D.
