3 1/2 pound = 7/2 pounds.
We know that the dog eats 7/2 (3.5) pounds every 21 days since there are 7 days in a week and Mr.Z only buys dog food every 3 weeks.
Set up a proportion. <u>3.5 lb</u> = <u> x </u><u>
</u> 21 days 365 days
<u>
</u>Cross multiply and divide. 3.5 lb x 365 days = 1277.5 / 21 days = 60.83 lb

Answer:
2(2x^2 - x + 1)
Step-by-step explanation:
you write you problem 9x^2 - 2x - 5x^2 + 2 = 2(2x^2 - x + 1)
You collect the like terms by subtracting their coefficients
(9-5)x^2
Subtract the numbers
4x^2
4x^2 - 2x + 2
Factor out 2 from the expression
2(2x^2 - x + 1)
