First:
2x + 2z = 4
2(x+z)=4
x+z=4/2
x=2-z
-x - y - z= -8
-(2-z)-y-z= -8 replace x
-2+z-y-z= -8 (cancel z)
-2-y= -8
6 = y
Then:
-4x + 4y + 5z = 7 replace x and y
-4(2-z)+4*6 + 5z = 7
-8 + 4z + 24 + 5z = 7
16 + 9z = 7
9z = 7 - 16
9z = -9
z = -9/9
z= -1
Finally
x= 2-z replace z
x = 2- (-1)
x = 3
Sqrt(2) = 1.41
so it would be between 1 and 2
Answer is A
Given, the plot is in the shape of triangle.
First side = x meter
Second side = ( 5x-3 )meters
Third side = ( 7x-6 ) meters
Perimeter of triangle is equal to the sum of all the three sides.
Perimeter =
Combine like terms by adding all the x terms together and all the constant terms together.
Perimeter =
Perimeter = feet ... Answer
Perimeter = sum of all sides
32 = 2(x+2) + 2(7)
32 = 2x+4 + 14
32 = 2x+18
14 = 2x
/2 /2
7 = x
