Question
Add:
3y2 − 10y + 16; 2y − 7
Solution
(3y2 − 10y + 16) + (2y − 7)
= 3y2 − 10y + 16 + 2y − 7
= 3y2 + (−10y + 2y) + (16 − 7)
= 3y2 + (−8y) + 9
= 3y2 − 8y + 9

At age of 2 years, a cat or a dog is considered 24 “human” years old. Each year, after age 2 is equivalent to 4 “human” years. Fill in the expression [24 + `square` (a – 2)] so that it represents the age of a cat or dog in human years. Also, you need to determine for what ‘a’ stands for. Copy the chart and use your expression to complete it.
