Explanation

Every constant term in an expression has degree 0 because it has no variable part.

The degree refers to the highest power of the variable in the term; constants have no variable, so the degree is zero.

Explanation

The ratio of circumference to diameter of any circle is a constant known as π (pi).

It is approximately equal to 3.14.

Pi (π) is an irrational number.

This meaning its decimal expansion never ends or repeats.

It is crucial in geometry, trigonometry, and engineering.

Explanation

Explanation

Smallest 3-digit number is 100; smallest 2-digit number is 10.

Their product is 100 × 10 = 1000.

Explanation

Equal sets must have exactly the same elements.

Same number but different elements means they are not equal → A ≠ B.

Explanation

"Sum of six and z" means 6 + z.

"Less than four" means the expression is less than 4 → 6 + z < 4.

Explanation

Explanation

The product of two integers of the same sign is always Positive.

Same sign (both positive or both negative) multiplication gives positive result.

Opposite signs give negative product.

Additional information:

The product of two integers of unlike signs is always negative.

Explanation

Given the proportion:

6 : x :: 9 : 12

We can write it as:

6/x = 9/12

Cross-multiplying:

6 × 12 = 9 × x

72 = 9x

x = 72/9

x = 8
