Do anyone know how to do this?​
kykrilka [37]

Answer:

1.) x=4

2.) x=14

Step-by-step explanation:

FOR #1:

1.) In order to solve the parallelogram, you must know that each opposite sides must equal...

so KL=JM and KJ=LM

2.) To solve for "x", you must substitute

 KL= 7x-2\\JM=12x-22

so it should end up with...

7x-2=12x-22

3.) Solve the equation with some algebra

7x-2=12x-22\\-5x=-20\\x=4

FOR #2:

1.) In order for a square, rectangle, parallelogram, (or any shape with four sides), it must equal to 360°. And you just have two given angles, which equal to 180, so that means the unknown equals to 180...So in this case you should have

(3x+5)+(9x-17)+180=360

as your equation...

2.) Solve with algebra

(3x+5)+(9x-17)+180=360

3x+5+9x-17=180\\12x-12=180\\(\frac{1}{12}) 12x=168 (\frac{1}{12})\\x=14

<u><em>multiplied</em></u>

How many solutions can a single variable linear equation contain?
Burka [1]

Answer:

One solution

Step-by-step explanation:

As a generalization:  an equation of degree n has n solutions.  A quadratic equation has the second degree and thus two a solutions; a third degree equation has three, and so on.  Thus, a first degree (linear) equation has one solution.
