Yes they are congruent because they have the same size angle and have the same parallel sides
Yes because K is a variable not a number
13.) (t⁻⁴)⁻⁹t² Now if the exponents outside of the parenthesis, that means you multiply them. t⁻⁴⁽⁻⁹⁾=t⁴⁵ Next, When it look like this: t⁴⁵ · t², don't multiply! When it comes to this, you had to add the exponents because it has the same base number: t⁴⁵⁺²=t⁴⁷.
Here's your answer to your question, t⁴⁷.
Answer:the 3rd one
Step-by-step explanation:
The least possible degree of polynomial is 2
