Step-by-step explanation:
2*5 3* 5 4*5 = 10 15 20
9*5 -1*5 -7*5 45 -5 -35
11*5 5*5 -3*5 55 25 -15
First we are going to group the terms that contains the common factor

in one parenthesis, and the other ones in another parenthesis:


Notice that our the terms in our first parenthesis have a common factor

, and the terms in our second one have the common factor

. Lets factor those out:

Now we have a common factor

in both terms, so we can factor those out as well:

We can conclude that the completely factored expression ordered alphabetically is

.
Answer:
x = 109
Step-by-step explanation:
The figure has one pair of parallel sides and is a trapezoid.
The lower base angle is supplementary to the upper base angle on the same side, thus
x + x - 38 = 180 , that is
2x - 38 = 180 ( add 38 to both sides )
2x = 218 ( divide both sides by 2 )
x = 109
