Question

Identify in the given expressions, terms which are not constants. Give their numerical coefficients.
(i) 5x - 3
(ii) 11-2y²
(iii) 2x - 1
(iv) 4x²y + 3xy²-5​

with steps​

Answer 1

Answer:

Constants: The terms which are free from variables.  

Numerical coefficient: Number multiplied with a variable.  

(i)    Constant = -3  

Term which is not constant = 5x  

Numerical coefficient = 5  

(ii) 5x-3  

Constant = 11  

Term which is not constant =  

Numerical coefficient = -2  

(iii) 11-2y squared  

Constant = -1

Term which is not constant = 2x  

Numerical coefficient = 2  

Therefore, the terms which are not constants are 5x,-2y squared,2x   respectively and their numerical coefficients are 5, -2, 2 respectively.

Answer 2

Answer:

1. 5

2. 2

3. 2

4. 4 and 3

Step-by-step explanation:

coefficient is a number before a variable so,

the coefficient of 5x is 5.

2y^2 = 2

2x = 2

4x = 4   &  3xy = 3.
