4 + 8 = 12 is correct.
N = x4 x8 = x4+4 = (x4)2 = N2
9 x 4 = 36
I would get 12 to be safe.
70 ft2 * 4 ft = 19,600 cubic feet
It is: 3*4 = 4*3 which is the same as 12 = 12
4 + 8 = 12 is correct.
x4-8 = 0 x4 = 8 Eradicate the the power of 4 x = 1.681792831 Check: 1.6817928314 = 8.000000009 which is just about correct.
N = x4 x8 = x4+4 = (x4)2 = N2
30 times 4 equals 120
9 x 4 = 36
X3xX4=X3+4=X7 this is the correct answer.
If: x4 = 5 Then: x = 1.4953487812
I would get 12 to be safe.
if 4 * 7 = x * 4, then x = (4 * 7) / 4 = 7
( -12 x8 y8 ) / ( 3 x4 y2 ) = -4 x4 y6
y = 3x = 12y = 12
