Answer 1

Answer:

perimeter=(4y-3x+2z)

1st side is (4x+2y+z)

2nd side is (3x+7y-2z)

Let 3rd side be A

Step-by-step explanation:

perimeter=1st side +2nd side + 3rd side

(4y-3x+2z) =(4x+2y+z) +(3x+7y-2z) + A

(4y-3x+2z)= {(4x+3x) +(2y+7y)+ (z-2z)} + A

(4y-3x+2z)= (7x+9y-z)+A

A= (4y-3x+2z)-(7x+9y-z)

A=(4y-9y)-(-3x-7x)-(2z-z)

A=-5y+10x-z

we can also write this as 10x-5y-z

Answer 2

(4x+2y+z) + (3x+7y-2z) = (4y-3x+2z)

4x +2y+z + 3x+7y-2z = 4y-3x+2z

4x+3x+2y+7y+z-2z = 4y-3x+2z 7x+9y-z=4y-3x+2z . = 9y-4y-z-2z = -3x-7x = 3y-3z= -10x
