KL = 4x +3.<br> JK = 4x + 2, and<br> JL = 45<br> Find KL.
lbvjy [14]

Answer:

KL=23

Step-by-step explanation:

We are given the length of the whole line and its two halves. Since JK and KL make up the line JL, adding them together would make the line JL.

(4x+3)+(4x+2) = 45

8x+5=45

8x=40

x=5

Now we can plug the value of x back into the expression we were given for the line KL.
