elena55 [62]

Answer:

A = 62.35 cm²

Step-by-step explanation:

Use the area formula A = \frac{\sqrt{3}a^2}{4}, where a is the side length.

Plug in the values:

A = \frac{\sqrt{3}(12^2)}{4}

A = \frac{\sqrt{3}(144)}{4}

A = 62.35 cm²

How are polynomials like and unlike monomials? Provide an example of a monomial and an example of a polynomial. How does the fol
Ainat [17]
A polynomial is the sum of at least one term. For example, x^3+1 is a polynomial. A monomial is a polynomial with only one term, such as 2x^2. A binomial is a polynomial with two terms, and a trinomial is one with three terms. The example you gave is a trinomial (which is also a polynomial). Degree of a polynomial is the largest sum of variable powers in any term of the polynomial. So, for example, x^2 y has degree 3, and x^3+x^2 also has degree 3. A sixth degree polynomial would be x^6-2x+1, for example.
