Answer: 15, 16, 17

Step-by-step explanation: you have to divide 48 by 3 when you do this then you get the center number in this case 16 so all you have to do now is add the lower number (15) and the higher number (17) and add and they will equal 48

(K² – 30k - 18 - 4K²) ÷ (3+k).

Alexxandr [17]

Answer:

$k^2-30k-18-4k^2=(k+3)(-3k-21)+45$

Step-by-step explanation:

Given:

$(k^2-30k-18-4k^2):(3+k)$

Consider the expression $k^2-30k-18-4k^2$ . First, add the like term $k^2$ and $-4k^2:$

$k^2-4k^2=-3k^2$

Now, this expression is

$-3k^2-30k-18$

Divide $-3k^2-30k-18$ by $k+3.$ Multiply $k+3$ by $-3k$ and subtract the result from the $-3k^2-30k-18$ to eliminate the highest term $-3k^2:$

$-3k^2-30k-18-(-3k)(k+3)=-3k^2-30k-18+3k^2+9k=-21k-18$

Multiply $k+3$ by -21 and subtract the result from $-21k-18:$

$-21k-18-(-21)(k+3)=-21k-18+21k+63=45$

Hence,

$k^2-30k-18-4k^2=(k+3)(-3k-21)+45$

Answer: A. have the same slope

Step-by-step explanation:

b. bisect means right in half but not fully intersecting kinda looks like this _l_ *oh and it asked you to prove that they bisect so clicking on it don't really make sense*

c. perpendicular means there is four equal angels and that is 90 degree angels

d. parallel... well it's obviously not parallel because parallel are two lines that are exactly the same but never intersect

*intersect means touch*
