Hello there!

Whenever you see a variable (letter) without a number in front of it, the "number" would be 1!

Example:

a = 1a


So simply do basic math! For now, ignore the letters!

2a + a + 2a + a

becomes

2 + 1 + 2 + 1

Once you have your answer, simply add an a to the end!

Your answer will have NO exponents because you're adding! If you were multiplying or dividing the variables, then exponents would be an issue.

Hope this helped! :)

What is the value of x?
hammer [34]

Answer:

16.

How to find... ↓

The small triangle is 1/3 size of the big triangle.

If this is the case, find the LCF here, 4, and multiply each angle's value by the least common factor, 4.

3 x 4 (bottom) = 12

5 x 4 (right side) = 20

4 x 4 (left side <em>the missing side) </em>= 16

Therefore,

The missing side value, <em>x</em>, is 16.
