Question

which is greater -
1 , 3a+4a or 7a-5a

2 , -3s - 4s or -10s + 3s


3 , 4pq² -3pq² or 6pq² -pq²

4 , 10u³v⁴ + 5u³v⁴ or 4u³v⁴ + 12u³v⁴
​

Answer 1

Answer:

plss follow me if you like my answer...

Step-by-step explanation:

1) 3a+4a

because ,. 7a-5a = 2a

but 3a+4a = 7a.

so , 7a >2a.

2) both are equal:

-3s - 4s = -10a+3s

=> 7s=7s

3) 6pq² -pq².

because:

4pq² -3pq² = pq²

whereas, 6pq² -pq²= 5pq²

so ,

6pq² -pq²> 4pq² -3pq²

4) 4u³v⁴ + 12u³v⁴

because: 4u³v⁴ + 12u³v⁴ = 16u³v⁴

whereas, 10u³v⁴ + 5u³v⁴ = 15u³v⁴

so,

4u³v⁴ + 12u³v⁴ > 10u³v⁴ + 5u³v⁴ .

3) 6pq² -pq².

because:

whereas, 6pq² -pq²= 5pq²

so ,

6pq² -pq²> 4pq² -3pq²

4) 4u³v⁴ + 12u³v⁴

because: 4u³v⁴ + 12u³v⁴ = 16u³v⁴

whereas, 10u³v⁴ + 5u³v⁴ = 15u³v⁴

so,

4u³v⁴ + 12u³v⁴ > 10u³v⁴ + 5u³v⁴ .
