<u>ANSWER:
</u>
After changing the side lengths of the triangle are decreased by scale factor of 3, the perimeter of triangle also decreased by 3
<u>SOLUTION:</u>
Given, the side lengths of a triangle are decreased by a scale factor of 3.
Let the side lengths of the given triangle be a, b, c.
After the side lengths are decreased by a scale factor of 3.
Now, the side lengths will become 
Before changing the side lengths, perimeter of the triangle is p = a + b + c.
After changing the side lengths, perimeter of the triangle is 
So, the perimeter is also decreased by the scale factor of 3.
Hence, after changing the side lengths of the triangle are decreased by scale factor of 3, the perimeter of triangle also decreased by 3.
Okay to find percentages of things you have to take that original value (1500) and multuply it by the percentage. But when you multiply you put the percentage into a decimal and move it over to the right side two decimal places to the left. For example 10.0% would mean you need to multiply by 0.10 okay?
So for this problem you need to do 1500 *.013 and you get 19.5 computers.
Answer:
Step-by-step explanation:
Por aspa simple:
x²+x-30=0
X +6
X -5
(x+6)(x-5)=0
x+6=0
x=-6
x-5=0
x=5

The area of a circle is pi times the radius squared (A = π r²). Example of calculating the area of a circle is in the image below.
A farmer has 15 boxes of eggs and there are 6 eggs in each box. Therefore it will be part to whole. The bigger number is always the whole. 6:15 is the ratio.
