Okay so that is the problem that my teacher gave me for solving QE using completing the square but I did it and it didn’t give me the same answer as her can someone help me and explain to me how to get it. Pleas I have a test on this Monday help!!!

My answer was
P = -2 +- 8i

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

the answers might not be correct use at own risk

113.1

step-by-step explanation:

v=4

3πr3=4

3·π·33≈113.09734
