Answer 1

Answer:

We have

(i) 3x + 7x = (3 + 7)x = 10x

(ii) -5xy + 9xy = ( -5 + 9)xy = 4xy

Answer 2

⋆HeyMate...!!

Step-by-step explanation:

Question:

Add the following:

(i) 3x and 7x

(ii) −5xy and 9xy

ANSWER:

We have

(i) 3x + 7x = (3 + 7)x = 10x

(ii) -5xy + 9xy = ( -5 + 9)xy = 4x

Question:

Simplify each of the following:

(i) 7x3y + 9yx3

(ii) 12a2b + 3ba2

ANSWER:

Simplifying the given expressions, we have

(i) 7x3y + 9yx3 = (7 + 9)x3y = 16x3y

(ii) 12a2b + 3ba2 = (12 + 3)a2b = 15a2b

hope it helps uh✌
