Question

Which of the following shows how the number 7 can be rewritten with the difference of squares identity? (16-9)=(4+3)(4-3) (18-11)=(9+6)(9-5) (25-4)=(5+2)(5-2) (16-9)=-1(4+3)(4-3) (64-1)=(8+1)(8-1)

Answer 1

A) (16-9) =(4+3)(4-3)

Explanation:

Explanation:-

Given the number = 7

The difference of two numbers are 16-9 =7

The difference of squares

4² - 3² = 7

We will use formula

a² - b² = (a-b) (a+b)

4² - 3² = (4 -3) (4+3)

16 -9 = (4 -3) (4+3)

Final answer:-

The number 7 can be rewritten with the difference of squares identity

16 -9 = (4 -3) (4+3)
