Can the set of numbers 8,12,4 make a triangle? And if it can, does it make a right triangle

Mathematics

bagirrra123 [75]3 years ago
4 0

Answer:

  No

Step-by-step explanation:

The sum of the shorter two lengths is exactly equal to the longer length. The "triangle" made by these segments will look like a line segment of length 12. It will have zero area.

Many authors would tell you this is <em>not a triangle</em>. (Others will tell you it is a triangle—a degenerate case.)

_____

These numbers are an arithmetic sequence. The ratio of lengths is 1 : 2 : 3. The only arithmetic sequence of side lengths that makes a right triangle are those in the ratio 3 : 4 : 5.

I will greatly appreciate if you can solve this question!

Answer: The answer would be B

<u>Write out the equation in slope-intercept form: </u>

y=-5/3x+6 (Once we know that, it'll be easier to convert it into standard form.)

<u>Subtract -5/3 from both sides of the equation:</u>

y+5/3x=6

<u>Subtract 6 from both sides:</u>

y+5/3x-6=0

<u>Multiply both sides by 3 to get rid of the fraction:</u>

3y+5x-18=0

<u>Then arrange the numbers to x and y are on one side by itself:</u>

3y+5x=18

<em>And that's your answer!</em>

Can someone help me?
soldier1979 [14.2K]

Answer:

Step-by-step explanation:

First your going to plug in what p and q are into the equation so 3(2)^5+10(-3)^2 over 7(2)+1.

Your going to first do (2)^5 and (-3)^2 so it’s going to be 3(32)+10(9) over (multiply the 7(2) first) 14+1.

3(32)+10(9) over 14+1 now multiply 3(32) and 10(9) you should get (96)+(90) over 15.

add 96+90 to get 186 over 15.

then divide how many times 15 can go into 186 you should get 12 6/15 and divide 6/15 by 3 to get your final answer 12 2/5.

I hope this helps!
