Answer:

23.82

Step-by-step explanation:

1) if the coordinates are: A(-5;4), B(0;3), C(4;-1) and D(4;-5), then it is possible to calculate the sides of the given quadretarial;

2) AB=sqrt(26)≈5.1; BC=sqrt(32)≈5.66; CD=4; AD=sqrt(82)≈9.06;

3) the required perimeter is: AB+BC+CD+AD=5.1+5.66+4+9.06=23.82 (units)

Substitute 3x+y=4 5x-y=22

Mrac [35]

Simultaneous Equations

3x + y = 4
5x - y = 22
The signs of the matching values aren't the same so we add the rest of the equations.
8x = 26
Divide both sides by 8 to get x = 3.25
Now substitute back into the first equation.
(3 x 3.25) + y = 4
9.75 + y = 4
Subtract 9.75 from both sides
y = -5.75
