Answer: y+2x=15
Step-by-step explanation:
Given
Two points A and B are (4,7) and (6,3) respectively
Using two-point form

Putting values

To simplify this, we first need to distribute the 2 into the parenthesis.
= 2 * x + 2 * 3 - 4
Now, we can simplify:
= 2x + 6 - 4
= 2x + 2

The scale model of a building 3 inches tall if the building is 90 feet tall is 2:5
<h3>Scaling of measurement</h3>
Scaling is the way of enlarging or reducing the image of an object.
Given scale model of a building is 3 inches, if the building is 90feet tall, to write the scale;
Convert both measures to same units
Since 1 feet. = 12 in
90 feet = 90/12 in = 7.5 in
Take the ratio
3 : 7.5 = 30: 75
Reduce to lowest term
30: 75 = 2 : 5
Hence the scale model of a building 3 inches tall if the building is 90 feet tall is 2:5

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:

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>):
12=2*2*3
45=3*3*5
15=3*5
10=2*5
L.C.M=2*2*3*3*5=180
required number 180+2=182
