Answer:
Step-by-step explanation:
We group the number 5:
5(x² + 3x + 2.25)
Now inside the brackets we'll take the square root of the coefficient of the x and the square root of the last number, then remove the square from the x and write it as a sum:
5(x+1.5)²
What's the idea behind this?
Well, remember that when you have something in the form:
(a+b)²
It actually means:
a² + 2ab + b²
In our case a was x, and b was 2.25. For bringing it into the shorter form we have to take the square root of a and b.
Sorry if you don't understand. Tell me if you need help to get the xoncept better.
Answer:
2) 12,000 ft²
3) 30 gallons.
Step-by-step explanation:
2) 1. You can calculate the lateral surface area of the exterior walls of the warehouse by applying the formula shown below:
Where <em>h</em> is the height, <em>l</em> is the lenght and <em>w</em> is the width.
2. Substitute values and you obtain that the lateral area is:
![LA=20ft[(2*200ft)+(2*100ft)]](https://tex.z-dn.net/?f=LA%3D20ft%5B%282%2A200ft%29%2B%282%2A100ft%29%5D)
3) You know that 1 gallon of paint covers 400 ft², therefore for 12,000 ft² are needed the following number of gallons (which is represented by <em>x</em>):
