Answer:
The perfect -square trinomial
(9y+7)²
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given polynomial equation
81 y² + 126 y +49
⇒ 9² y² + 2(9)(7)y + 7²
⇒ (9y)² + 2(9)(7)y +7²
we will use formula
(a+b)² = a² + 2ab +b²
⇒ (9y+7)²
<u><em>Final answer:-</em></u>
The perfect -square trinomial
(9y+7)²
Answer:
0.4, 0.8, 1.2 ,1.6 ,2.0
Step-by-step explanation:
First we have to find what the question is really asking and get rid of unwanted or not needed information. It is asking to write a numeric sequence for the first 5 minutes of the 30 minutes.
Second we need to find the pattern. So lets divide $12 by 30. That will equal 0.4 a minute.
Last we add 0.4 for each minute. 0.4 is the first, then 0.8 is 2 minutes, then 1.2 and etc.
