Answer:
26.2 units 
Step-by-step explanation:
We are given the points/vertices 
A(6, 3), 
B(6, - 2) , and 
C(- 4, 3)
Step two 
Let us find the distances between the given points/vertices
A-B =A(6, 3) to B(6,-2)
d=√((x2-x1)²+(y2-y1)²)
Substitute 
d=√((6-6)²+(-2-3)²)
d=√(-2-3)²)
d=√(-5)²)
d=5 units
B-C=B(6, - 2) to C(-4, 3)
d=√((x2-x1)²+(y2-y1)²)
Substitute 
d=√((-4-6)²+(3+2)²)
d=√(-10)²+(5)²)
d=√100+25
d=√125
d=11.2 units 
C-A=C(-4, 3) to A(6, 3)
d=√((x2-x1)²+(y2-y1)²)
Substitute 
d=√((6+4)²+(3-3)²)
d=√(10)²
d=√100
d=10 units 
Hence the perimeter is 5+11.2+10
P=26.2 units 
 
        
             
        
        
        
Answer:
8x+y
Explanation:
3x+4y+5x-3y
Rearrange the terms so like terms are next to each other
3x+5x+4y-3y
Combine like terms
8x+y
I hope this helps!
        
             
        
        
        
Answer:
Length:28 cm
Width: 13 cm
Step-by-step explanation:
Let
x ---> the length of a rectangle picture frame
y ---> the width of a rectangle picture frame
we know that
The area of a rectangle picture frame is equal to

we have

so
 ----> equation A
 ----> equation A
The length of a rectangle picture frame is 2 centimeters more than twice it’s width
so
 ---> equation B
 ---> equation B
Solve the system by graphing 
Remember that the solution is the intersection point both graphs
The solution is the point (28,13)
see the attached figure
therefore
Length:28 cm
Width: 13 cm
