Step-by-step explanation:
6.) 8p = 8x9 = 72
8.) 4(d+7) = 4(-2+7) = 4(5) = 20
can't read all of 10 to give an answer
I hope this helps you
a=4
b=9
c= -1
disctirminant =b^2-4ac
disctirminant =9^2-4.4. (-1)
disctirminant =97
x1=-9+square root of 97/2.4= -9+square root of 97/8
x2= -9-square root of 97/2.4= -9-square root of 97/8
Uhh my brains hurts looking at that
