900-144=756
square root 756
b=27.5
Addition bc. you need adding to both sides x and will get this result of 3x+2 = 11

Answer:
118%
Step-by-step explanation:
Cora's kitten weighed in the last visit to the veterinarian's office= 550 grams
Right now, Cora's kitten weighs = 1200 grams
Increase in the kitten's weight= 1200 - 550 = 650 grams
Percent increase in weight= 650/550 * 100
= 118.18% = 118%
Hence, there is 118% increase in kitten's weight.
