To add the variables, add the coefficients with same variable. The expression which is equivalent to given expression is
. The option 2 is the correct option.
<h3>What is
equivalent expression?</h3>
Equivalent expression are the expression whose result is equal to the original expression, but the way of representation is different.
Given information-
The expression given in the problem is,

Let the resultant expression of the above expression is
. thus,

To add the algebraic terms open the brackets first,

Separate the same variable terms,

To add the variables, add the coefficients with same variable. Thus,

Hence, the expression which is equivalent to given expression is
. The option 2 is the correct option.

I got -307 (if the x stands for multiplication)
Step-by-step explanation:
to find a common denominator, you have to find a number that "works" with every other number.
for example, say you have
2/4 and 8/12
First you need to find the common factor between 4 and 12, so list all your fours
4, 8, 12, 16, 20
Now list all your twelves
12, 24, 36, 48, 60
to find the common factor you look at both your list of numbers and find one that's the same, sometimes it takes a long list of numbers to find the common factor, but you will run into one.
So by looking at our list we see that 4 and 12 share the common factor of 12. but since 8/12 already has a denominator of 12, we are going to leave it alone.
now think about what you would multiply 4 by, to get to 12. The answer is
4 x 3 = 12
to make the numerator correct, you multiply it by the same number you did 4, so since your faction is 2/4 you should do 2 x 3 = 6
now you have your answer,
2/4 and 8/12 turns into
6/12 and 8/12
and that's how you find it, let me know if you have questions :)
Answer:
The answer is 
Step-by-step explanation:
We have to:

So, if we take the 60 degree angle of the smallest triangle, we have to:

We do not know x. But if we take the sine of the angle of 30 degrees and the main triangle we have:

Then:
