Answer 78
Step-by-step explanation:
Answer:
18
I am assuming you meant 8r-rs, in this case:
Plug in r=6 and s=5:
8(6)-(6)(5)
8*6 = 48 and -6*5= -30
Thus,
48-30= 18
y=6x
g=-9/2
c=0
y=-9/2x
3/4x*-9/2
D = - 9
D - 7 = -18
D - 7 + 7 = -18 + 7
D = -9
Answer
x=2 and y=2√2
380 if rounded to the nearest whole number
