Answer:
Step-by-step explanation:
// Build on Thu Oct 20 21:06:21 CEST 2011 for language "en"
myHostname = window.location.hostname;
var myTLD = "." + myHostname.substring(myHostname.indexOf("wupload") + "wupload.".length).split(".")[0];
function afterLoad() {
return
}
ieFixForFileSelectionOnChangeEventTimer = null;
function ieFixForFileSelectionOnChangeEvent(a) {
$("#siteName").toggle();
if ($("#inputFileSelection").val() == "") {
ieFixForFileSelectionOnChangeEventTimer = setTimeout("ieFixForFileSelectionOnChangeEvent()", 200)
} else {
$("body")[0].focus()
}
}
function urlencode(a) {
return escape(a.toString().replace(/%/g, "%25").replace(/\+/g, "%2B")).replace(/%25/g, "%")
}
5 - 6 = -1
2 + 7 = 9
-1 × 9 = -9
-9 would be the simplified answer.
Hope this helps!
In order to figure this out you need to use
Descartes Rule. I attached a picture showing Descartes Rule. If the signs changes for when x is positive then the number of times it changes are the possible positive solution. If the sign changes when x is negative then the number of times it changes are the possible negative solutions. With that said the answer is A. View the picture I have attached for the possible + - and imaginary solutions.
Answer = A) One possible positive solution.
You would have to add a positive 6 to the negative 6 to get zero. Lets say you have -2 in order to get it to zero or just any positive number, you have to add a positive of the same value or higher to be able to get it there. I hope you understand that.
