I need some help please! K is the midpoint or segment JL. JL=3x-15 JK=18 Find x.

1 answer:

4 0

Because K is the midpoint of JL and JK = 18, KL must also equal 18. So the equation would be 3x - 15 = 36 because you add 18 + 18. You then add 15 to both sides to get 3x = 51. Then you divide by 3 on both sides to get x = 17.

Answer:

x > -1

Step-by-step explanation:

Divide the whole inequality by 9.

( $\frac{x}{3}$ +1)> $\frac{6}{9}$

$\frac{x}{3}$ > $\frac{2}{3}$ - 1

$\frac{x}{3}$ > - $\frac{1}{3}$

Multiply by 3.

madreJ [45]

Answer:

$n^{3} + 15n^{2} + 56n$

Step-by-step explanation:

First FOIL (n + 7)(n + 8) and then distribute n

(n + 7)(n + 8) = $n^{2} +15n + 56$

n ( $n^{2} +15n + 56$ )

= $n^{3} + 15n^{2} + 56n$
