I don't know about square inches, I can't convert 128 inches to square inches is there anyway Google or something can help you?
Complimentary angles add up to 90 degrees
2x + 4x = 90
6x = 90
x = 90/6
x = 15 <==
Substituting z = 5 into the first equation:
2x - y + 5 = -4
y = 2x + 9
Substituting y and z into the third equation
-2x + 3(2x + 9) - 5 = -10
4x + 27 = -5
x = -8
y = 2(-8) + 9 = 7
z = 5
the answer is 1,522,447.06
hope I helped:)
