Let x = your number.
x^2 - 21 = 4x. Subtract 4x from both sides.
x^2 - 4x - 21 = 0. Factor.
(x - 7) (x + 3) = 0. Set each term to 0.
x + 3 = 0. Subtract 3 from both sides.
x = -3. This is the negative solution.
Set the other term equal to zero.
x - 7 = 0. Add 7 to each side.
x = 7. This is the positive solution.
Hai , you can use Pythagoras Theorem to find the length which is hypotenuse.
It will be 7^2 + 3^2 = 58
square root 58 and you will get 7.62
Hope this helps and i am sorry if my answer was wrong .
08 and get one and two left in ten right em
