Question

Which one of the following is an example of algebraic expression?
a. 22+7÷4
b. 12=7−1
c. x,y,z
d. x2+y−2

Answer 1

Answer:

Option D. x²+y-2

Step-by-step explanation:

Algebraic expressions include at least one variable and at least one operation (addition, subtraction, multiplication, division). For example, 2(x + 8y) is an algebraic expression.

Answer 2

Answer:

The correct option is choice D.  x^2+y−2

Algebraic expression means that equation needs to have one variable, meaning any alphabet and one kind of operation. Operations are + - / and*

If you look at your answer choices, option d is the only that has an expression as well as the operation, so both things in one equation.
