Tom sells baseball cards at 10 for 35 cents. Is that a better deal than 12 for 40 cents?

The expression that is not a polynomial is

A polynomial function is a function that is made up of non-zero coefficients, positive exponents, and constants.

Types of polynomials

1. Linear polynomial function: it is made up of one variable raised to the power of 1.

An example is y + 10

2. Quadratic polynomial function - it is made up of a variable that is raised to the power of two.  

An example is x² + 10x + 25

3. Cubic polynomial function: a single power is raised to the power of three.  

An example is 124y³ + y²

The following are not polynomials:

1. An expression that is divided by another variable.
2. An expression with a negative exponent
3. An exponent that is a decimal.

Answer:

A

Step-by-step explanation:

The rules of exponents say that a polynomial CAN'T have a variable as a denominator. Option A violates that rule, since it has x + 3 as a denominator.

Answer:

the measure of the missing angle is 60°

Step-by-step explanation:

GIVEN : j || k

solution :

We will use the property of linear pairs

120° + ∠1 = 180° (sum of linear pairs is 180°)

⇒ ∠1 = 180°- 120°

⇒∠1 = 60°

now since j || k

So, we can use corresponding angle properties

So, ∠? = ∠1 (corresponding angles are equal)

⇒∠? = ∠1  = 60°

Thus ? = 60°
