The measurement indicated in each

LM=12

V =90

Step-by-step explanation:

4.  If it is a parallelogram, the two sides have to be equal.

2x-6 = x+3

Subtract x from each side

2x-x -6 = x+3-x

x-6 =3

Add 6 to each side

x-6+6 = 3+6

x=9

LM =2x-6

    = 2*9 -6

   = 18-6

   = 12

5.  

<U + < T = 180   Adjacent corners in a parallelogram are supplementary

11x+2 + 12x-6 = 180

Combine like terms

23x -4 = 180

Add 4 to each side

23x-4+4 = 180+4

23x = 184

Divide by 23

23x/23 = 184/23

x=8

<V = <T  Opposite corners in a parallelogram are equal.

<V = 12x-6

<V = 12(8) -6

<V = 96-6

<v =90

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
