If two angles and the included side of one triable are congruent to the corresponding parts do another triangle then the triangles would be congruent now if two angles and the non-included side of one triangle are congruent to the corresponding parts of another triangle then the triangles would be congruent. Hope this helps a bit:)

Answer:

1. x =8

2.  x=9

Step-by-step explanation:

Since these figures are parallelograms, the opposite sides are equal.

1.     6 = 2x-10

Add 10 to each side

   6+10 = 2x-10+10

   16 = 2x

Divide  each side by 2

16/2 = 2x/2

 8 =x


2.  x+14 =23

    Subtract 14 from each side

x+14-14 = 23-14

x = 9

What is the simplified expression for Negative 3 (2 x minus y) + 2 y + 2 (x + y)?
Lana71 [14]

Answer:

7y - 4x

Step-by-step explanation:

-3 (2x-y)+2y+2(x+y)\\

Step 1:  Open the brackets

= -6x+3y +2y +2(x+y)\\=-6x +3y + 2y +2x + 2y

Step 2: Bring the similar variables together

=-6x +2x \ +3y + 2y + 2y

Step 3: Simplify by adding/subtracting the coefficients of the similar variables

= - 4x +7y

Step 4: Rearrange as required.

Simplify the expression by combining like terms. <br><br>4y+7x- 2y+4x​
juin [17]

Hello!

Answer:

\boxed{2y+11x}

Step-by-step explanation:

Distributive property: a(b+c)=ab+ac

<em>First, you switch sides. *Group like terms*</em>

4y-2y+7x+4x

<em>Then, you add the similar to elements. You can also add the numbers from left to right.</em>

4y-2y=2y

2y+7x+4x

7x+4x=11x

\boxed{2y+11x}\checkmark, is the correct answer.

Hope this helps!

Have a nice day! :)
