Can 12 cm 12 cm and 28 cm form a triangle
erastova [34]
Using the Theorem of Pythagoras (a² + b² = c²)

Put in the values:

12² + 12² = 28²
Is it correct? (solve)

Nope! Because 12² + 12² = 288, and the square root of 288 is about 17, not 28.

The answer is no, 12cm, 12cm, 28cm cannot form a triangle.

Hopefully this helps! If you have any more questions or don't understand, feel free to DM me, and I'll get back to you ASAP! :)

1)How many ways can the letters in the word BOOKKEEPER be arranged? (Must show set-up )
sergeinik [125]
Question 1

There are 5 letters (B, O, K, E, R) and there is a total of 10 letters to make up the word.
There are \frac{10!}{(10-6)!6!} ways of arranging the letters, which equal to 210 ways

Question 2

There are seven swimmers in total.
There are \frac{7!}{(7-1)!1!} ways of choosing the first winner, which is 7 ways
There are \frac{6!}{(6-1)!1!} ways of choosing the second winner, which is 6 ways
There are \frac{5!}{(5-1)!1!} ways of choosing the third winner, which is 5 ways
There are 7×6×5=210 ways of choosing first, second, and third winner

Question 3

The probability of eating an orange and a red candy is \frac{15}{31}×\frac{9}{30}, which equals to \frac{9}{62}

The probability of eating two green candies is \frac{7}{31}×\frac{6}{30} which equals to \frac{7}{155}

#82 will give brainliest to best answer!​
Fofino [41]

Answer:

\frac{6}{k-6}

Step-by-step explanation:

First, we can factor all of the following equations to turn that weird, huge looking thing into \frac{(k+6)(k-6)}{(k-6)(k-10)} ÷ \frac{(k-6)^2}{k(k-6)} × \frac{6(k-10)}{k(k + 6)}. We know that division is simply multiplication by the reciprocal, so that whole equation will turn into \frac{(k+6)(k-6)}{(k-6)(k-10)} × \frac{k(k-6)}{(k-6)^2} × \frac{6(k-10)}{k(k+6)}. Now we can cancel out some values if they are both in the numerator and denominator, which will turn that still huge looking thing into \frac{6}{k-6} which is our final answer, as it cannot be simplified further.

Hope this helped! :)
