Answer:
ac/b
Step-by-step explanation:
1) X²+5X-50=0
↠X² + 10X -5X -50 = 0
↠X(X+10)-5(X+10) = 0
↠(X-5)(X+10)=0
↠X = 5, -10
2)B²+6B-16=0
↠B² + 8B - 2B -16 = 0
↠B(B+8) -2(B+8) =0
↠(B-2) (B+8) =0
↠B = 2,-8
3)R²+6R+8=0
↠R²+4R+2R+8=0
↠R(R+4)+2(R+4)=0
↠(R+2)(R+4)=0
↠R=-2,-4
4) P²+5P+6=0
↠P²+3P+2P+6=0
↠P(P+3)+2(P+3)=0
↠(P+2)(P+3)=0
↠P=-2,-3
Pretty much saying 5+ (x*10)_<-25
I would say that the tree is 12 feet high.
And to find out the answer you could use the quadratic formula :)
