to get the answer of this is to change the whole thing to algebra that is Let put an X as unknown squared number X * X + 23 =104 subtract 23 from both sides X * X + 23 - 23 = 104 - 23 X * X = 81 Now find the square root of 81. the square root of 81 is 9. check: 9 * 9 + 23 = 104
The square footage, or area, of a 14' x 23' rectangle would be 322' squared.
If: x+x2 = 110 then x = 10 which is the solution
The perimeter of a square with sides of 23 centimetres is equal to 23 x 4 = 92 centimetres.
√207 = √9 x √23 = 3√23
