How do I solve this problem
Ronch [10]

\overline{LK}\cong\overline{MK}\\LK=MK=7x-10\\KN=x+3\\MN=9x-11\\KJ=28\\\\MN=MK+KN\\\text{therefore we have the equation:}\\9x-11=(7x-10)+(x+3)\\9x-11=8x-7\ \ \ |+11\\9x=8x+4\ \ \ \ |-8x\\x=4

LJ=LK+KJ\\\\LK=7x-10\to LK=7(4)-10=28-10=18\\\\\text{therefore}\\LJ=18+28=46

Answer: LJ = 46.

Which polynomial matches the expression -x(x – 5)?
Art [367]

Answer:

-x² + 5x

Step-by-step explanation:

Distribute -x to all terms within the parenthesis. Note that when multiplying a negative variable and a positive variable, the result is a negative variable. Also note that when multiplying a negative variable with a negative number, the result is a positive.

(-x)(x) = -x²

(-x)(-5) = 5x

-x² + 5x is your answer.
