3/5 both 12 and 20 can both be divided by 4
Answer:
true
Step-by-step explanation:
if the vertical lines are not parallel, then the corresponding angles are not congruent.
8x + 2 = 14x - 76
8x - 14x = -76 -2
-6x = -78
x = 13
8(13) + 2 = 14(13) - 76
106 = 106---- equal
the vertical lines is a bit confusing.... they looks like not a parallel lines
Answer:
Yes, 40/25 is equivalent to 32/20.
Given:
Consider the expression is
![231^2-131^2](https://tex.z-dn.net/?f=231%5E2-131%5E2)
To find:
The value of given expression using a suitable identity.
Solution:
We have,
![231^2-131^2](https://tex.z-dn.net/?f=231%5E2-131%5E2)
Using the identity
, we get
![231^2-131^2=(231-131)(231+131)](https://tex.z-dn.net/?f=231%5E2-131%5E2%3D%28231-131%29%28231%2B131%29)
![231^2-131^2=(100)(362)](https://tex.z-dn.net/?f=231%5E2-131%5E2%3D%28100%29%28362%29)
![231^2-131^2=36200](https://tex.z-dn.net/?f=231%5E2-131%5E2%3D36200)
Therefore, the value of the given expression is
.
2x - 7 = 2x - 14
2x = 2x - 7.
