Bruh I already answered this https://web2.0calc.com/questions/let-p-x-x-2-q-x-2x-3-1-and-r-x-7x-4-5x-3-6x-2-find-p-q-x-r-x#r1
Solve the quadratic and take the positive root to get 10.175.
RS = 58-12 = 46.
Did you mean (2-x)? If you did, then the max is 81 at x=-5/2.
\(\angle VTU, \angle UTV\)
Use AM-GM for positive x,y, we can get that x+y>=6, and for negatives x+y<=-6.
So, it is either x+y>=6 or x+y<=-6.
Not math related as it matters where you actually live, like if you are in florida you could go to the carribean, but if you are in california you couldn't.
\(A = \frac{2+7}{2} \cdot 4 = 18\)
Hint: The slope of line CD is 1. Then, you can set up two equations using the area and the slope of line CD.
I would just bash out the coefficent of x^15 in (x+x^2+x^3+x^4+x^5+x^6)^5
You get 651 :)
