a. 42 and 42
b. 42 and 288
c. 1,764 and 1,764
d. 4,202 and 4,248

Answer 1

Answer:

The answer is B. 42 and 288

Step-by-step explanation:

165^2 - 123^2

165 x 165 = 27225

123 x 123 = 15129

27225 - 15129 = 12096

42 x 288 = 12096

Answer 2

$42$ and $288$  are the numbers that should be multiplied to obtain $165^2 -123^2$

What are numbers?

A number is a mathematical object used to count, measure, and label. The original examples are the natural numbers 1, 2, 3, 4, and so forth. Numbers can be represented in language with number words.

According to question, we have to find the numbers  that should be multiplied to obtain $165^2 -123^2$

Now,    $165^2 -123^2$

       $=27225 - 15129 = 12096$

Also,$42$ × $288 = 12096$

On both case, we get the results as  $12096$

Hence, Option (B) is correct.
