Question
Tell me the answer
Find Out More Vou have evaluated expressions with known numbers and operation signs. An example of this would be 6-7×4. Now you will evaluate expressions that include variables. Remember, a variable is a letter that stands for an unknown number. Look at this expression. coefficient variable constant 2x+5 term term Every expression is made up of terms. A term is a known number, a variable, or the product of a known number and variable(s). The expression 2x + 5 has two terms: 2x and 5. A term that is a known number without variables is called a constant. The expression 2x + 5 has one constant: 5. A term that includes variables is called a variable term. The expression 2x + 5 has one variable term: 2x. If one factor of a variable term is a known number, that number is called the coefficient. The coefficient of the term 2x is 2. Look again at the term 2x. It means "multiply a number by 2." You have used the symbol x for multiplication. However, now that you are using the variable x, you will need other ways to show multiplication. The expression 2 X x would look confusing. Instead, you can write 2 x or 2x. Reflect 1 Claire says the expression 8x³ has three terms: 8, x, and 3. Is she correct? Explain.
