Thank you both so much for the help.
Yra it works perfect with the code modification you made.
In case anyone else is interested, this code was added in Protean-> Styles-> Custom styles:
.bx-form-input-captcha > div {

 transform: scale(0.77);-webkit-transform: scale(0.77);transform-origin: 0 0;-webkit-transform-origin :0 0;

width: 220px;

}
