Find the value of n such that each expression is a perfect square trinomial for each of the following questions
1) p^2 - 6p + n
2) m^2 - 8m + n
3) v^2 + 24v + n
4) y^2 - 40y + n
5) v^2 - 36w + n

The answers are below

Step-by-step explanation:

1) p² - 6p + n =  p² - 6p + (3)² = (p-3)²         n = 9  

2) m² - 8m + n  = m² - 8m + (4)² = (m-4)²       n= 16

3) v² + 24v + n  =  v² + 24v + (12)² = (v + 12)²   n=144

4) y² - 40y + n  = y² - 40y + (20)² = (y - 20)²    n= 400

5) v² - 36w + n =  v² - 36w + (18)² = (v - 18)²  n = 324

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.

sorry i don't know the other answer. i didn't learn what a proportional relationship is.
