Answer:

Q3. Option (C)

Q4. Option (C)

Step-by-step explanation:

Q3. A polynomial is an expression consisting of variables and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables.

By this definition, only option (C) is a polynomial.

Q4. 3a - [4b + 6a - (7a - (8b - 2a))]

= 3a - [4b + 6a - (7a - 8b + 2a)]

= 3a - [4b + 6a - 9a + 8b]

= 3a - [-3a + 12b]

= 3a + 3a - 12b

= 6a - 12b

Answer:

1. (c)

2. (c)

Step-by-step explanation:

Q2. 3a - [4b + 6a - (7a - (8b - 2a))

= 3a - [4b + 6a - (7a - 8b + 2a)]

= 3a - [4b + 6a - 9a + 8b]

= 3a - [-3a + 12b]

= 3a + 3a - 12b

= 6a - 12b

Pls mark as brainliest, rate, thank and follow me ✌️✌️✌️
