Step-by-step explanation:
The area of triangle with vertices is given by
Then area of triangle QRS with vertices (6,10), (2,-10) and (-9,5) is given by :-
I would know ur answer but I can't really see
Answer:
26 sq. ft.
Step-by-step explanation:
So 6 1/2*4
6*4=24, 1/2*4=2
24+2=26
1) X^5Y/X^5= X^0Y= Y (Anything raise to power of 0 is 1)
2)(3mn)^1= 3mn
3)m^-4xM^5= M^-4+5= M
4) 5^-4x5^4= 5^-4+4= 5^0= 1
5) nm^3/n^3m= n^1-3m^3-1= n^-2m^2= m^2/n^2
6) (-2)^0= 1
therefore number 4 and 6 has the value of 1
