Solve for x in the equation x2 + 4x-4-8 . O x= -6 or x = 2
X=-2+2 V2
O x= -2 or x = 6
O x=2+2√2
X=2+

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
