Answer:
A) 
Step-by-step explanation:
Given expression:

To factor the given expression completely.
Solution:
In order to factor the expression, we will factor in pairs.

We will factor the G.C.F of the terms in the pairs.
G.C.F. of
and
can be given as:


Thus, G.C.F. = 
G.C.F. of
and
can be given as:


Thus, G.C.F. = 
The expression after factoring the G.C.F. pairs is given as:

Taking G.C.F. of the whole expression as
is a common term.

The expression is completely factored.
X + x - 32 = 180
2x - 32 = 180
2x = 212
x = 106
x - 32 = 106 - 32 = 74
the other 2 angles = 90
137
you multiply 20 by 8 which you get 160 then you subtract 23 and then your answer is 137
Answer - 30x-18
Explanation: you multiply six by all the numbers in parentheses, and since there are no like terms, you leave it as 30x-18. Hope this helps
The correct answer is b. c=6k+55
