Question

Please answer the question

Answer 1

1+(8+4)= ( 1+8)+4

After you , equate , divide you'll get 0

Answer 2

20 - B) x = 3

21 - C) 2 × 0 = 0

Step-by-step Step-by-step explanation:

20 - Find the value of x :

`\quad{\implies{\bold{ - 3(4 - 2x) = 6}}}`

`\quad{\implies{\sf{ -12 + 6x = 6}}}`

`\quad{\implies{\sf{6x = 6 + 12}}}`

`\quad{\implies{\sf{6x = 18}}}`

`\quad{\implies{\sf{x = (18)/(6)}}}`

`\quad{\implies{\sf{x = \cancel{(18)/(6)}}}}`

`\quad{\implies{\sf{x =3}}}`

Hence, option B) x = 3 is the correct answer.

21 - Which of the following is an example of the zero property?

• A) 1.2 + -1.2 = 0
• B) |-3| = 3
• C) 2 × 0 = 0
• D) 1 + (8 + 4) = (1 + 8) + 4

Option C) 2 × 0 = 0 is the correct answer.
