Answer:
3u(u - 2)
Step-by-step explanation:
greatest common factor: 3u (both are divisible by 3, and include the variable u)
factor: 3u^2/3u = u; -6u/3u = 2
new polynomial: 3u(u - 2)
The question asks us to find the area of a triangle. First, before we do anything, we need to state the formula for the area of a triangle, which is
, where
is the base and
is the height. In this scenario, we are given the length of the height, which is
. We need to find the length of KL, which is the base. We can see that this triangle is a 30, 60, 90 degree triangle, meaning that it has some special properties. First off, it means that the hypotenuse is two times the side opposite to it, which in this case is that AL (the hypotenuse) is two times the length of AK, which is the side opposite to it. Thus, the length of the hypotenuse is
. Now, we can use the Pythagorean Theorem to find the length of the base.
Now that we found all the required values for the formula, just plug it in and solve. When we do so, we get that the area is
. Hope this helped!
Answer:
= 6n - 2
Step-by-step explanation:
Because you can use the formula = a1 + d (n - 1) to identify the arithmetic sequence :)
3 to the 1st is 3,
3 to the 2nd is 9,
3 to the 3rd is 27,
3 to the 4th is 81,
3 to the 5th is 243,
3 to the 6th is 729.
