Answer 1

Answer:

1.48xy,2.30ab

Step-by-step explanation:

1.21xy+27xy=48xy

2.24ab+6ab=30ab

Answer 2

The answers are, 16x³y and 15a²b, respectively.

Given : The given algebraic expressions are :

• 7x³y + 9yx³
• 7x³y + 9yx³12a²b + 3ba²

To find : Simplifications of the given algebraic expressions.

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to simplify the given algebraic expressions)

So,

= 7x³y + 9yx³

= 7x³y + 9x³y

= x³y (7+9)

= x³y × 16

= 16x³y

And,

= 12a²b + 3ba²

= 12a²b + 3a²b

= a²b (12+3)

= a²b × 15

= 15a²b

(These will be considered as the final results. Both of the algebraic expressions cannot be further simplified.)

Hence, the answers are 16x³y and 15a²b, respectively.
