Question

please try to solve this sum please std 8​

Answer 1

Answer:

7p²q² - 3pq + 16 + 2 + 5pq - 5p²q²

7p²q² - 5l²q² - 3pq + 5pq + 16 + 2

2p²q² + 2pq + 18

for b part a - 3b + 2ab + b -c + bc + 7c - 4a + ac

a - 4a - 3b + b + 2ab + ac - c + ac

-3a- 2b + 2ab + 2ac - c

for 2nd question

price of 12 bananas is a-5

and bananas needed is b + 8 dozen

we need to find the price

price will be a-5/12

and banans needed is b + 8 × 12

so a-5/12×12 when bananas are b + 8

so a - 5 / b + 8

a - 5 + 5 / b + 8 + 5

a / b + 13

so total price is b + 13
