Answer:
12/5
Step-by-step explanation:
His fish tank is 4 1/2 gallons of water. It takes him 1 7/8 minutes to fill it. So you need to find out how many gallons you can pour in 1 minute. You can eliminate A because he is filling more than 1 gallon per minute. You can divide 4.5 (4 1/2) by 1.875 (1 7/8). You get 2.4. Convert it back to a fraction, and you get 2 4/10. Simplify the fraction 2/5. Now convert it to an improper fraction. 12/5.
<span>x^2 + 22x + 121 = 9 + 121 ..............a^2 + 2ab + b^2 = (a+b)^2
(x + 11)^2 = 130
answer
</span><span>you must add 121 to complete the square</span>
