Find the value of KL.<br> KL= 3x + 2 and LM= 5x - 10
Mariana [72]

From the given graph, we can tell kl=lm 

therefore,

3x + 2 = 5x - 10

3x+2-2=5x-10-2 

subtract 2 from both sides. 

3x+ 0 =5x-12 3x=5x-12 

3x-5x=5x-5x-12 

subtract 5x from both sides.

-2x=0-12 -2x=-12 (-2x)/-2=-12/-2 

divide both sides by -2. 

1x= 6 -12/-2=6 

and of course the -2 and -2 cancel on left side leaving 1x. 

x=6

KL = 3x+2 = 20 units

Find the number of real number solutions for the equation x^2-6=0
andrew11 [14]

Answer:

Step-by-step explanation:

x^2-6=0

x^+6=0 ( add six to both sides)

x^2=6

x= the square root of 6 ( to get rid of the exponent you have to do the opposite....which is the square root)

x=2.44948974278

You may have to round if not given the exact number.

Step-by-step explanation:

again, a line cutting through 2 parallel lines must have the exact same angles with both of them. otherwise they would not be parallel.

therefore, both angles must be identical

3x + 2 = 2x + 6

x = 4
