The partial circles in each corner mean that all 3 angles are identical, which means this is an equatorial triangle. In an equatorial triangle all three sides are the same.
We can set two of the equations to equal each other and solve for x:
3x -5 = 2x +20
Add 5 to each side:
3x = 2x +25
Subtract 2x from each side:
x = 25
 
        
             
        
        
        
Just use teh same numbers as the perimeter and times it by 7 and 5

Answer: Choice A)  <9,0></h3>
Explanation:
Focus on one of the points in the figure on the left. Let's say we go for the upper left corner point (-7, 4)
Notice it moves to the corresponding image point (2,4). It has shifted 9 units to the right to follow the translation rule  . We've added 9 to the x coordinate, and the y coordinate stays the same.
. We've added 9 to the x coordinate, and the y coordinate stays the same.
This notation can be shortened to <9, 0>
In general, the notation  is shortened to the translation vector notation
 is shortened to the translation vector notation  . In this case, a = 9 and b = 0.
. In this case, a = 9 and b = 0.
 
        
        
        
Answer:
55
Step-by-step explanation:
The absolute value of -30 is 30 and the absolute value of 25 is 25.
So you will end up with 30 + 25 which is 55.
