Answer:
- 10b² + 12b - 16
Step-by-step explanation:
b² + 8b - 9 - (11b² - 4b + 7) ← distribute by - 1
= b² + 8b - 9 - 11b² + 4b - 7 ← collect like terms
= (b² - 11b²) + (8b + 4b) + (- 9 - 7)
= - 10b² + 12b - 16
So what you need to do is take a protractor and use it to measure angle c
Write 343 w/ an exponent by using 7 as the base.
7^3
It would be answer 3. sorry if it’s wrong
Density is the correct answer.
