What are “like terms”? Why can we only add like terms?

Mathematics
1 answer:
SSSSS [86.1K]3 years ago
4 0

Answer:

Like terms are terms whose variables are the same.

We can only add them because if they does not have the same variable you do not actually know if the variables are equivalent and you will get the wrong answer.

Step-by-step explanation:

Ex: 4z,7z,108z,45z

Ex: 4w-2h+7a-2w

You can not add 4w and 7a because you do not know what the variables equal so you do not know the true number so add or subtract by.

The base and height of the triangle to the right are multiplied by 4. Describe the change in the area.
Artemon [7]
Area would be 15 if base is 6m and height is 5m
So 6*4=24
5*4=20
Area would be 240 for the 2nd answer

240/15=16

The area is 16x bigger

Help Please.Use complete sentences to explain the steps required in converting 180 degrees to its equivalent radian measure. Inc
Phoenix [80]
To convert 180 degrees to its equivalent radian measure, multiply it with π/180.
180 (π/180)
The result is π radians.
This is also how the other angles in degrees are converted to radians. Simply multiply with π/180 and express the result in terms of pi.<span />
