WILL GIVE BRAINLIEST! Find k so that (5, k) is equidistant from (–1, 2) and (3, 0).

pochemuha

Answer:

Step-by-step explanation:

So first I created 2 distance forumlas and set them equal to each other

$\sqrt{(5+1)^2+(k-2)^2} =\sqrt{(5-3)^2+(k)^2}$

then I simplified them

$(5+1)^2+(k-2)^2 =(5-3)^2+(k)^2\\$

$36 + k^2 - 4k +4 = k^2 + 4$

$-4k + 36 = 0\\$

$4k = 36$

$k = 9$

when k = 9, the two distances are equal

- x² - 4x + 12 = 0 <br>how do u solve by completing the square

MrRa [10]

Answer:

Step-by-step explanation:

Simplifying

x2 + -4x + -12 = 0

Reorder the terms:

-12 + -4x + x2 = 0

Solving

-12 + -4x + x2 = 0

Solving for variable 'x'.

Factor a trinomial.

(-2 + -1x)(6 + -1x) = 0

4th grade math. Help?!

viva [34]

Answer: Well... does it give you the approximate length or actual length of the butterfly? If so, you would take that length and multiply it by 5. That would give you the length of the 5 butterfly lined up together.

If it does not give you the approximate length or actual length, look up the length on google. (Google Answer- Size: 2.5" - 4.0" range.)

Take that and multiply it by five to get the length of the 5 butterflies.
