Pavlova-9 [17]3 years ago

Answer:

Overall vertical is visually better, if done correctly

it forces you to "line up" all the common exponents.

The disadvantage is that it usually requires re-writing the problem, and it takes up space.

most problems are presented horizontally, that becomes the issue to locate the common exponents.

in both cases the biggest issue is people forget

that when subtracting "subtracting a negative is like adding a positive"

-5x - (-8x)  = 3x [that is a positive 3x]

or:

     -7x

-    - 10x

-------------

     3x

everyone misses those eventually so you have to watch out for that in both methods

Step-by-step explanation:

Find the value of x in the triangle shown below. x = 56° 99°​
anyanavicka [17]

Answer:

x = 25 degrees

Step-by-step explanation:

All angles in a triangle should add up to 180 degrees. So to solve for x, set up an equation where all three angles added up equals 180.

180 = 99 + 56 + x

180 = 155 + x

25 = x

The unknown angle is equal to 25 degrees.
