Answer:
Two solutions (-4,-7) and (4,7)
Step-by-step explanation:
x = y + 3
x*y = 28
(y+3)*y=28
y^2+3y-28=0
(y+7)(y-4)=0
y=-7, y=4
x=-4, x=7
Yes because all sides would be equal to 5 which would give you 5*4 = 20 units.
R = dt
/d /d
R/d = t
I think again
-35x = -105
divide -105 by -35 to get x by itself
x = 3
The answer is false because the real answer would be 3
