Question

3. Write the numerical coefficient of the terms:
a) 2x + 7y
b) -p2q2 + 9pq
c) 2.2a + 0.6 b​

Answer 1

Answer:

(a) coefficient of x in 2x = 2

coefficient of y in 7y = 7

(b) coefficient of pq in -p2q2 = 4

coefficient of pq in +9pq = 9

(c) coefficient of a in 2.2a = 2.2

coefficient of b in 0.6b = 0.6

Answer 2

Step-by-step explanation:

Given:-

a) 2x + 7y

a) 2x + 7yb) -p2q2 + 9pq

a) 2x + 7yb) -p2q2 + 9pqc) 2.2a + 0.6 b

To find:-

Write the numerical coefficient of the terms?

Solution:-

a) Given expression is 2x+7y

The numerical coefficient of 2x=2

The numerical coefficient of 7y=7

b)Given expression is -p2q2 + 9pq

The numerical coefficient of -p²q²= -1

The numerical coefficient of 9pq=9

c) Given expression is 2.2a + 0.6 b

The numerical coefficient of 2.2a=2.2

The numerical coefficient of 0.6b=0.6
