Answer:

3x - 3

Step-by-step explanation:

Hello!

The first thing you want to do is REMOVE the parentheses, because they are not needed. The equations in them have already been FULLY SIMPLIFIED.

But, DON'T throw those parentheses away! Our next step is to RE-ARRANGE our terms. Have the 'x terms' on one side, and the constants on the other, putting those parentheses around the two. Your equation should look like:

(x + 2x) + (4 - 7)

Our final step is to simplify.

(1)x + 2x = 3x

4 - 7 = -3

Therefore, your final answer is 3x - 3

Hope this helped!

Answer:

3x - 3

Step-by-step explanation:

(x + 4) + (2x - 7) =

The first step is to drop the parentheses since they are unnecessary.

= x + 4 + 2x - 7

Now group like terms together.

= x + 2x + 4 - 7

Combine like terms.

= 3x - 3

Identity the congruence statement for the triangles below.
GalinKa [24]

<u>Answer:</u>

Triangle HMK≅Triangle ILJ

<u>Explanation:</u>

Two triangles are congruent if they have the same sides and the same size. This means they have the same shape and size, regardless of their position or orientation.


If we want to verify if two triangles are congruent, they must fulfill some conditions:


a) Two triangles are congruent if their three sides are respectively equal



b) Two triangles are congruent if two of their sides and the angle between them are respectively of equal length.



c) Two triangles are congruent if they have a congruent side and the angles with vertex at the ends of that side are also congruent.  


d) Two triangles are congruent if they have two sides respectively congruent and the angles opposite the greater of the sides are also congruent



According to these criteria, Triangle HMK≅Triangle ILJ
