Are you able to cancle 65-x in the following fraction?

(65-x)/(65-x)(65-x)+x^2-250

Are you able to cancle one of the top 65-x with the bottom one?

Yup , you can :D

anonymous · Answer

yes u can cancel it

chaise · Answer

Okay - I still need help. Assume I have this question

anonymous · Answer

yes you can. you can cancel when there is multiplication, not addition.

chaise · Answer

I thoguht so
cos^-1((65-x)/(65-x)(65-x)+x^2-250)

We cancel one of the 65-x we get:

cos^-1(1/65-x+x^2-250)

We gather like terms?

cos^-1(1/x^2-x-185)

Use the quadratic formula to solve for x. you get two answers of

94 degrees and 86 degrees? Can someone pls double check?

chaise · Answer

When solving for x in the denominator you get:

x = (1-sqrt(741))/2
x = 1+sqrt(741)/2

cos^-1(1/x) = 86 and 94?
