A.) Simplifying the equation would lead you to 15x^2-3x+9
b.) You know your answer is correct because you're adding the two polynomials together. 9x^2+6x^2 is 1tx^2. Now you have 2x-5x and since the negative is bigger, you get -3x. Then 5+4 is 9. You have no like terms therefore your answer is 15x^2-3x+9
The number you are looking for is 1
Answer:
I can answer the first one the other 2 I can't make out.
Step-by-step explanation:
Firstly,
1) They are the same since they add one to the row every time
2) They are different because Megan's pattern is that they only count the first column in orange, and Kyle's pattern counts the number of blocks in each row.
3) They have the same number of blocks just in different colors in rows and columns.
Answer and step-by-step explanation:
20. Because the discount is 20% of the given price so the discount would be"
228/100*20
= 45.6 Rs
Its selling price would be:
228 + 45.6 = 273.6 Rs
21. Sales tax would be:
450/100*5
= 22.5 Rs
Total price in bill = 22.5 + 450 = 472.5 Rs
22. 10% tax of 3300 would be:
3300/100*10 = 330 Rs
Price before tax = 3300 - 330 = 2970 Rs
23. He spent in total of:
2500 + 500 = 3000Rs
He sold for 3300 Rs
He gain 3300 - 3000 = 300 Rs profit
His loss gain percent = 3300/3000 * 100 = 110%
24. On the first bike, he earn:
2500/100*20 = 500 Rs
On the second bike, he lose:
2500/100*25 = 625 Rs
He lose in total of 625 -500 = 125 Rs
his loss percentage = (2500+500) + (2500 - 625) / 5000* 100
= 100% - (2500+500) + (2500 - 625) / 5000* 100
= 100% - 97.5%
He lose 2.5% money
Hope this helped :3
