The hundred thousandth place is 1. Since 2 comes after it, and 2 is less than five, then it rounds down, making the answer 100,000.
9 ten-thousands is 9*10,000=90,000. 90,000/10 is 9,000, or nine thousands.
Answer: 12b
Step-by-step explanation: you multiply 4 by 3 but keep the b
= (7u³ + 8u² + 7) + (8u³ - 3u + 7)
Operate like terms together:
= 7u³ + 8u³ + 8u² - 3u + 7 + 7
= 15u³ + 8u² - 3u + 14
In short, Your Answer would be: 15u³ + 8u² - 3u + 14
Hope this helps!
