Answer:

that is true because A parallelogram has two pairs of parallel sides. A quadrilateral has interior angles that add up to 360 degrees. A square has four equal sides and four right angles. A kite is a parallelogram only when it is a rhombus.

Simplify the following equation completely. Write your answer in only positive exponents.

Answer:

Appears to be A with a typo.

Should be $\frac{3a^{12}*b^{3}}{4}$

Step-by-step explanation:

To evaluate or simplify expressions with exponents, we use exponent rules.

1. An exponent is only a short cut for multiplication. It simplifies how we write the expression.

2. When we multiply terms with the same bases, we add exponents.

3. When we divide terms with the same bases, we subtract exponents.

4. When we have a base to the exponent of 0, it is 1.

5. A negative exponent creates a fraction.

6. When we raise an exponent to an exponent, we multiply exponents.

7. When we have exponents with parenthesis, we apply it to everything in the parenthesis.

We will use these rules to simplify.

$\frac{12a^8b^{-7}}{(4a^{-2}b^{-5})^2}\\\\\frac{12a^8b^{-7}}{4^2a^{-4}b^{-10}} \\\\\frac{12}{16}*\frac{a^8}{a^{-4}}*\frac{b^{-7}}{b^{-10}}\\\\\frac{3}{4}*a^{8--4}*b^{-7--10}\\\\ \frac{3}{4}*a^{12}*b^{3}$
