Answer: 919
Step-by-step explanation: I set up a cross multiplication equation. I set 55 over 100 equal to 505.45 over X. I cross multiplied and did 505.45 times 100, which is 50,545. I then did 50,545 divided by 55 to get the answer of 919.
Answer:
(ab+10+a)-(6ab×6ab-2ab+8)
=ab+10+a-6ab×6ab+ab-8
=ab+10+a-36a²b²+2ab-8
=36a²b²+(ab-2ab)+a+(10-8)
therefore the answer is 36a²b²+3b+a+2
