The order of operations helps keep answers for multi-step equations similar. If the proper order of operations are not followed, then answers may vary. To show an example:
4 / 2 - 1
The proper order of operations would be:
Divide first, before subtracting
4 / 2 - 1
2 - 1
1
But if subtracting was done before dividing:
4 / 2 - 1
4 / 1
4
So not following the proper order would yield different and erroneous answers.
Answer:
The answer would be x=7.5
Step-by-step explanation:
Answer:
in figure 1 the value of X is 20° and figure 2 the value of X is 19° and y is 123°
Step-by-step explanation:
it is shown in the above process.
hope you understand
Yes it's quadratic because x which is after y is squared
