Sos i literally have no idea how to do 9-! if anyone knows how plz . u so much❤️❤️❤️

So before we jump into these problems, we must keep this particular rule in mind:

So remember that the perimeter is the sum of all the sides. In this case:

So firstly, using the product rule of radicals we need to simplify these radicals as such:

Now, combine like terms (since they all have the same like term √3, they can all be added up):

Your final answer is 17√3 in.

For this, we will be using the pythagorean theorem, which is , where a and b are the legs of the right triangle and c is the hypotenuse of the triangle. In this case, √18 and √32 are our legs and we need to find the hypotenuse. Set up our equation as such:

From here we can solve for the hypotenuse. Firstly, solve the exponents (remember that square roots and squared power cancel each other out):

Next, add up the left side:

Lastly, square root both sides of the equation:

The hypotenuse is √50 cm.

Now, the process is similar to that of 9 so I will just show the steps to the final answer.

The perimeter is 12√2 in.

Now, the process is still similar to question 9 but remember that this time we are working with cube roots.

Note that when adding the numbers together, 3 isn't a like term to the other 2 terms because it doesn't have ∛3 multiplied with it.

The perimeter is 3 + 12∛3 in.

  q

step-by-step explanation:

each line from a vertex to the midpoint of the opposite side is called a median. the point where the medians intersect, point q, is the centroid.

the centroid of δabc is point q.

points are handed out whenever you post answers.

brainliest answers are handed out by the person asking the question, so whether your answer is picked depends entirely on whether the asker bothers to pick

if you're asking about your rank, it depends on having a certain number of points and a certain number of brainliest answers. for example, at the time of this writing, i have 44338 points out of 15000 needed for the next (nearly triple the requirement! ) but i only have 24 out of 50 required brainliest answers. this number decays, meaning after a certain amount of time (i think about a month), the total number of brainliest answers you've earned doesn't count toward this total. (i've been stuck at the same rank for a long

the lesson to learn here is that you shouldn't worry about points or rank. chances are, no matter how good an answer you may provide, your efforts will go mostly unnoticed unless you focus on the newest/most active questions that get posted.
