Answer:
Any expression doesn't have the same value
Step-by-step explanation:
<h3>1. 23-82</h3>
Subtract 82 from 23.
−59
<h3>2. 23 - (8 x 2)</h3>
Simplify each term.
Multiply 8 by 2.
23−1⋅16
Multiply −1 by 16.
23−16
Subtract 16 from 23.
7
<h3>3. (23 -8) x 2</h3>
Subtract 8 from 23.
15⋅2
Multiply 15 by 2.
30

What is inside the square root? Is it just the root of x? Or is it ROOT(x-4) + 5 = 2?
As the question say this problem is a practice of the law of cosines!
The law of cosine: c^2=a^2+b^2-2ab*cos*c for any side a, b and c
The law can also be written as c=sqrt(a^2+b^2-2abcosc)
Now use this formula!(note cos 100 degrees is about 0.8623)
c=sqrt(15^2+16^2-2*15*16*cos100)
solving this we can MN is about 23.75
Round this to the nearest tenths now!
We get 23.8!
Thus the answer is D
Perimeter of a square=4*side length
2=4*side length
2/4=side length
.5 or 1/2=side length

<u>Percentage Calculations
</u>
One tricky fact about percentages is that they are usually performed over the last computed quantity. It makes them non-additive. For example, a raise of 10% followed by a 10% some time later, is NOT a 20% of total raise
The question states Ashely is making $500 a week at her job and that she receives a 20% pay raise. After that raise she will make
A year later she takes a 5% pay cut. We must be careful to take that percentage from the last earnings. She now makes
