Isometry - distance preserving injective map between metric spaces
Direct Isometry - orientation is preserved - the order of the lettering in the figure. and the image are the same , either both clockwise or both counterclockwise.
Opposite Isometry - orientation is not preserved - the order of the lettering is reserved , either clockwise becomes counterclockwise or counterclockwise becomes clockwise. Line Reflection

Alice wanted to solve for x by getting rid if the +8. explain and correct Alice error

ra1l [238]

Answer: The value of x will be 2.

Step-by-step explanation:

To calculate the value of 'x' or solve for x, we need to isolate x from 8.

In the equation, 8 is in addition with 'x' so for isolating it, we need to apply the reverse operation of addition.

Reverse operation of addition is subtraction.

We need to subtract 8 from both sides of the equation, we get:

$x+8-8=10-8\\\\x=2$

By doing this, we get the value of 'x' as 2.

Error done by Alice was that she added 8 and it did not led to the isolation of 'x'.

Is this correct? I just started learning this

MrRa [10]

2^3 = 8
3^2 = 9
5^2 = 25
2^5 = 32

(5^2 = 5*5 = 25)
(2^5 = 2*2*2*2*2 = 32)
