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.

F(x) = -3x^2 + 6x. Find f(2).
inysia [295]

Answer:

f(2) = 0

Step-by-step explanation:

Evaluate the function at x = 2.

f(x) = -3x^2 + 6x

f(2) = -3(2^2) + 6 * 2

f(2) = -3(4) + 12

f(2) = 0
