<u><em>Answer:</em></u>
DE is the common side in the two triangles
<u><em>Explanation:</em></u>
The side of the triangle is named based on its start and end points
A triangle is named based on its three vertices where each two vertices would join forming a side
<u>For ΔDEC, the sides are:</u>
DE, EC and DC
<u>For ΔEDB, the sides are:</u>
ED, DB and EB
By comparing the two triangles, we would find that DE is the common side in both triangles

Answer:
38.9
Step-by-step explanation:
Lets say, first number = x
Second number = 3x+7
Total = 49
(x)+(3x+7)= 49
4x+7 = 49
4x = 42
x = 42/4
x= 10.5
x= 10.5
3x+7 = 3(10.5)+7 = 38.9
Hope this helps!!
The second. 4(8) it should be 32. not 48.
Answer:
Option 4
Step-.by-step explanation:
Reflection over the y-axis is given by (x, y) ------->(-x, y). (the y-value stays the same)
So (-1, 3) ------> (1, 3).
TH answer is option 4.
<em>Answer: 24 </em>
<em>Step-by-step explanation:</em>
Equation: (1/3)x + 4 + 12 = x
Equation: (1/3)x + 16 = x
MULTIPLY EVERYTHING WITH 3
1/3 times 3 = x 16 times 3 = 48 x times 3 = 3x
Equation: x + 48 = 3x MINUS THE "X" BY 3X = 2X
Equation: 2x = 48 OR x = 24
CHECK THE EQUATION:
Sister: 8 Brother: 4 Herself: 12
8 + 4 + 12 = 24
