the expression equivalent to 2x + 8 is (x+4) + (x+4)

using the commutative property we can say that

2x +8 = x + x + 8

also 2x + 8 = x + 4 + x + 4

hence 2x + 8 = (x+4) + (x+4)

<h3>What is an expression?</h3>
  • Mathematical statements are called expressions if they have at least two terms that are related by an operator and contain either numbers, variables, or both.
  • Addition, subtraction, multiplication, and division are all possible mathematical operations.
  • There are two sorts of expressions in mathematics: numerical expressions, which only contain numbers, and algebraic expressions, which also include variables.
  • In a mathematical expression, the following terms are used:
  • An absolute numerical number is referred to as a constant.
  • Variable: A symbol without a set value is referred to as a variable.
  • Term: A term can be made up of a single constant, a single variable, or a mix of variables and constants multiplied or divided.
  • a number that is multiplied by a variable is referred to as a coefficient.

Use the law of cosines to find the length of a
borishaifa [10]

Answer:

Step-by-step explanation:

You don't need the Law of Cosines, the Law of sines if what you need. You can't use the Law of Cosines because in order to find side a, you would need the length of side c and you don't have it. Using the Law of Sines is appropriate, knowing that angle B = 55:

\frac{sin55}{175}=\frac{sin42}{a} and solving for a:

a=\frac{175sin42}{sin55} so

a = 143.0
