Answer:

x=3\text{ or } x=-15

Step-by-step explanation:

So we have the equation:

|2x+12|=18

Definition of Absolute Value:

2x+12=18\text{ or } 2x+12=-18

Subtract 12 from both sides for both equations:

2x=6\text{ or } 2x=-30

Divide both sides by 2 for both equations:

x=3\text{ or } x=-15

And we're done!

Consider △LNM. Which statements are true for triangle LNM? Check all that apply. The side opposite ∠L is NM. The side opposite ∠
Anvisha [2.4K]

The following statements are true by definition:

The side opposite ∠L is NM.

The side opposite ∠N is ML.

The side opposite to the angle should not contain any letter of that side.

 

<span>The following statements are not essentially true because we have no idea if triangle LNM is a right triangle (if it is, then we do not know what the hypotenuse is):</span>

The hypotenuse is NM.

The hypotenuse is LN.

 

<span>The following statements are not true:</span>

The side adjacent ∠L is NM.

The side adjacent ∠N is ML.

They are not true because the side adjacent to an angle should have its letter on the side. For example, the side adjacent to ∠L should be LN or LM and for ∠N it should be NM or NL.

Help me please help please me and
Ad libitum [116K]

Answer:

x=148

Linear pairs add up to 180. Take your value of 32 and subtract it from 180 to find out the value of the remaining angle within the linear pair.

180-32=148

Hence, x=148

Hope this helps!

IM Not too sure on this. can someone please help me out?
DENIUS [597]
All it is asking is to plug the given x values into the equation (which are 0, 2, 4) and see what you get for y.
4y - 2x =16

4y - 2 (0) = 16
4y = 16
y = 4

4y - 2 (2) = 16
4y - 4 = 16
4y = 20
y = 5

4y - 2 (4) = 16
4y - 8 = 16
4y = 24
y = 6

so D
