Answer:

(x + 15) / 2

Step-by-step explanation:

Distance = rate × time

d = (x² – 225) / (2x − 30)

d = (x – 15) (x + 15) / (2 (x – 15))

d = (x + 15) / 2

Can some help me with this math problem

Answer:

This is true when the shape is a cube because all the faces are equivalent. This isn't true when it is a rectangular prism because some faces have areas larger than other faces.

0.14m= how many cm. get it right please
givi [52]
Here, I'll show you an EASY conversion acronym:
Kangaroos, Hopping Down Mountains Drinking Chocolate Milk:
That is KHDMDCM.
Now, here's what they ACTUALLY stand for:
Kilo, (kilometers, kilograms, etc.), Hecto, (hectograms, hectometers, etc.), Deca, (decameters, decagrams, etc.), M stands for THREE things, Meters, liters, and grams, Deci, (decimeters, decigrams, etc.), Centi, (centimeters, centigrams, etc.), and Milli, (millimeters, milligrams, etc.).
Now, you look at the diagram I have provided below:
You put 0.14 under Meters, liters, and grams, because it's 0.14 meters.
Now, whenever you move RIGHT, you move the decimal RIGHT every time you move. If there is a WHOLE number, (like 14), you add a ZERO to the number, so when you would move 14 to the RIGHT, it would become 140. Now when you go LEFT, you move the decimal to the LEFT, and if there are ANY ZEROS, you would take them out.
Now you might get a little confused when moving left;
Look, EVERY NUMBER has a decimal, like the number 14 itself.
14 has an imaginary decimal, which is 14.0. EVERY NUMBER HAS THAT. So, if you are moving LEFT, and you DON'T have any zeros, you would simply have 14 into 1.4.
So, with that out of the way, let's start figuring out how many centimeters 0.14 is equivalent to.
So we move to the RIGHT, because the centimeters is on the RIGHT, and now we move the decimal to the right.
Now it would be 01.4, but it's the same as 1.4, so we'll just put 1.4 under deci.
Now we have 1.4 DECIMETERS, but not quite yet centimeters.
We must keep moving to the right.
Once we move that decimal AGAIN, it is now 14. 
WOO HOO! WE FIGURED IT OUT!
So 0.14m = 14 cm.
You saw how we figured that out? You could use this technique on ANY conversion problem like this in the future!
I hope I helped! =D

At a local toy store, you can build your own stuffed teddy bear. You can choose from 5 colors of bears, 3 different sizes and 12
Black_prince [1.1K]
The number of different types of bears that can be made using the given is calculated through the fundamental principles of counting. 

    n = (number of colors)(number of sizes)(number of t-shirts)

Substituting the known values,

   n = (5)(3)(12) = 180

Therefore, there are 180 different types of bears that can be made.
