Question

anonymous · Answer

think about it. Call your number x and express the sentence in the form of an equation.

anonymous · Answer

post what you got here.

anonymous · Answer

ive got nothing.

anonymous · Answer

would it be like , x-36=5x ?

anonymous · Answer

you are almost there. are you sure the LHS is x-36?

anonymous · Answer

x squared?

anonymous · Answer

yes.

anonymous · Answer

then bring over the 5x to the LHS and you have got yourself a quadratic equation. solve for x. The positive root is your answer.

anonymous · Answer

when i bring the 5x over would the equation be : xsquared-5x-36?

and thats not a face I tried to type

anonymous · Answer

lol okay

anonymous · Answer

yes, this is an equation. you always have a LHS and RHS for an equation.

myininaya · Answer

you can see if it is factorable or you can use the quadratic formula

radar · Answer

It is factorable$$x ^{2}-5x-36=0$$$$(x-9)(x+4)=0$$
Take it from there and get the solution(s)
