Answer:
£199.95
Step-by-step explanation:
100% - 69% = 31%
31% of £645
= 31/100 × £645
= 0.31 × £645
= £199.95
= £199.95 is the final answer as it cannot be rounded off to 2 DP.

5b^3(4 - 9b^2)
Use the distributive property
=(5b^3)(4) + (5b^3)(-9b^2)
= 20b^3 - 45b^5
= -45b^5 + 20b^3
Have a nice day!
