15 percent of 760 is 114
760 - 114 = 646
Hope this helps :D
Use o fato de que o determinante de qualquer matriz quadrada é o mesmo da sua transposta.


-10d^2 + 11d - 2
To find this, distribute the - to 7d^2 - d - 6.
This will give you a new equation of:
-3d^2 + 10d - 8 -7d^2 + d + 6
Combine like terms to get the answer above.
Hope this helps!
29.9999 would be the answer here's how i worked it out
