Order of operations are:
<span>1. Parentheses (simplify inside 'em)
2. Exponents
3. Multiplication and Division (from left to right)
<span>4. Addition and Subtraction (from left to right)
So, on your first one:
Parentheses first:8(3+4)-2*8/(5-3)
8(7)-2*8/(2)
There are no exponents so multiplication and division:56-16/2
56-8
Finally, addition and subtraction:56-8=48
Your second problem is a bit more complicated but follows the same rules:

<span><span>
Parentheses first:</span></span>

Now, exponents. Even though they are inside parentheses, we can't go further until we simply those.
(64+81)/5
Now back to parentheses:(145)/5
Division:
145/5=29

Answer:
Option A
Triangles ABC and TUV
Step-by-step explanation:
Given three triangles ABC , FGH and TUV
For triangles ABC and FGH, given that
DF =AB
DH = AC
and angle F = angle A
This cannot be taken as SAS congruence because the angle F is not included between the equal sides. Two triangles can be congruent by SAS only if two sides and included angle are congruent.
For triangles ABC and TUV we have AB=TU, AC = TV and
included angles between these sides are equal.
So these two triangles are congruent
We write corresponding sides only in order Hence ABC = TUV
and Not VTU =ABC
So option A is true.
Answer:
Option "D" is correct.
Step-by-step explanation:

To eliminate negatives
They are interchanged thus it gives us option D.
