' = foot
8 feet by 8 feet
An area of 64 square feet
Assuming you mean 84 This means eight to the power of four. That is 8 x 8 x 8 x 8 = 4096
the mean is the average; (9 +8+4 + X)/4 = 8; solve for X ; (21 +X)/4 = 8; X = 11
8/x = x/24x2 = 8 x 24 = 192x = sqrt(192) = 13.8564 (rounded)
Eight cubed means: 8 x 8 x 8 = 512 Eight squared is: 8 x 8 = 64 Eight to the fourth power would be: 8 x 8 x 8 x 8 = 4096 it is the same as 83 (if you didn't know how it looked)
If you mean (11x -8)+7(x -1) then it is 18x -15 when simplified
If you mean: x-8 = 3 then x = 11
27 x x 8 Multiply 27 * 8 Multiply x * x 216 = x^2 Solve!
X is 8 Points in Scrabble
If you mean: x+8-x+9 when x = 5 Then it is: 5+8-5+9 = 17

√8 x √36 = 2.82842712474619 x 6 = 16.9705627484771
x + 5x + 6x = 12x. There are 3 terms. If the arithmetic mean is 8 then 12x = 3 x 8 = 24 : So, x = 24 ÷ 12 = 2.
Since you used no parentheses, I will assume that x over 2 minus 1 equal 8 means (x/2)-1=8 [It could also mean x/(2-1)=8: x/1=8: x=8] (x/2)-1=8 add one to both sides x/2=9 multiply both sides by two x=18
If you mean: y = x+4 and y = 3x+8 then x = -2 and y = 2
If you mean: x-3 = 2x-8 then the value of x works out as 5
