Which value must be added to the expression x2 + 12x to make it a perfect-square trinomial? 6 36 72 144
Answers
A perfect square trinomial can be factored into this form: (x+a)^2Note that (x+a)^2 = x^2 + (2a)x + a^2To find the missing number, we should take the 12 (in the 12x term) and divide it by two to get 6. This number squared will be the missing number at the end of the trinomial.
Let's check that this is the correct answer.(x+6)^2 = x^2 + 12x + 36Indeed, 36 is the correct answer."

When they ask you to fund the unit rate, it will typically be in some sort of measurement or price (pounds, inches, dollars, miles, etc.). They want you to find out how much one individual item would be, whether it's how much money, or how many inches, etc.
In this case, they want you to find the average amount of snow fallen in one day. Since it has been 10 days and 80 inches were dropped, you would divide the total amount of inches by the total amount of days in order to find how many inches were dropped in just one day.
