A greenhouse that specializes in growing vegetables used for Chinese cooking is divided into sections. The number of plants in each section depends on the number of sprinklers in that section.In a section with y sprinklers there are y(4y − 1) napa cabbage plants and (y + 5)2 bok choy plants.
Which simplified expression represents the total number of napa cabbage plants and bok choy plants in a section with y sprinklers? (5 points)
A.4y4 − 10y2 + 25
B.4y2 + 9y + 25
C.5y2 − 11y + 25
D.5y2 + 9y + 25
Answers
Napa Cabbage = y (4y-1) = 4y^2 - y
Bok Choy = (y+5)^2 = y^2 + 10y + 25
= 4y^2 - y + y^2 + 10y + 25
= 5y^2 + 9y + 25
The simplified expression represents the total number of napa cabbage plants and bok choy plants in a section with y sprinklers is 5y^2 + 9y + 25

Answer: x ≤ 5
Step-by-step explanation:
Our task is to solve the following inequality:
Remember that in every equation and inequality, we need to isolate x. To isolate x, we need to follow these steps:
- add 6 to each side
- divide each side by 8
--------------
step one
--------------
Add 6 to both sides:
--------------
step two
--------------
Divide both sides by 8:
{answer}. You're done! ^^'
Final answer:
To solve the inequality 8x - 6 <= 34 using the addition and multiplication principles, follow these steps: add 6 to both sides, then divide both sides by 8. The solution is x <= 5.
Explanation:
To solve the inequality 8x - 6 <= 34 using the addition and multiplication principles, you need to isolate the variable x. Here are the steps:
- Add 6 to both sides of the inequality: 8x - 6 + 6 <= 34 + 6 → 8x <= 40
- Divide both sides of the inequality by 8: 8x/8 <= 40/8 → x <= 5
Therefore, the solution to the inequality is x <= 5.

Step-by-step explanation:
Let's use the variable Y to represent the length of time (in seconds) that the traffic light remains yellow at a speed of x miles per hour. According to the information given, the time the light is yellow (Y) is 1 second more than 0.05 times the speed limit (x). We can write this as:
Y = 0.05x + 1
In this equation:
Y represents the length of time the light is yellow in seconds.
x represents the speed limit in miles per hour.
The equation shows that the time the light is yellow increases linearly with the speed limit, with an additional 1-second buffer.
