Answer:
If 9 of the sparrows is 45% of the birds in the backyard, 9/x = 45/100.
Cross multiply to get 9 * 100 = 45x; simplified is 900 = 45x or 20.
This means that there are 20 birds in the backyard. You can check this by dividing 9/20 which equals 45%

<span> (3x</span>² <span>+ 8) - (2x</span>² <span>+ 1)

= 3x² - 2x² + 8 - 1
= x² + 7
