Hi there!
Simplify th' Eqn.
(9x² + 2x - 5) + (6x² - 5x + 4)
⇒ 9x² + 2x - 5 + 6x² - 5x + 4
⇒9x² + 6x² + 2x - 5x - 5 + 4
⇒ 15x² - 3x - 1
Hence,
The simplified form is = 15x² - 3x - 1
~ Hope it helps!
Answer: 165.
Step-by-step explanation: You can multiply 11 by 15 to get 165. If that is too difficult, you can multiply 11 by 5 and 11 by 10 and add them. 11*5 is 55 and 11*10 is 110. 110 + 55 = 165.
