Step-by-step explanation:
Law of Cosine:
x squared=92 squared+42 squared-2(92)(42)(cos 141)
x squared =8464+1764-7728(cos 141)
x=127 cm

Step-by-step explanation:
An expression is a number, a variable, or a combination of numbers and variables and operation symbols. An equation is made up of two expressions connected by an equal sign.
-14 + 6b + 7 - 2b= 1 + 5b
combine like terms
-7 +4b = 1 + 5b
subtract 4b from each side
-7 + 4b -4b = 1 + 5b -4b
-7 = 1 + b
subtract 1 from each side
-7 -1 = 1-1 + b
-8 = b
