Answer: what kind of math is it tho?
I assume your "reasons" mean "roots" or "zeros"
if 3 is a root, plug x=3 in the equation, you can find n:
3²+(n-1)*3+6=0
3(n-1)=-15
n-1=-5
n=-4
Plug n=-4 in the original equation: x²-5x+6=0
factor: (x-3)(x-2)=0
x=3, which we already know
or x=2, which is the value of m+4
m+4=2
m=-2
Answer:
h = 16 inches
Step-by-step explanation:
The surface area of a cylinder is given by
SA = 2 pi r^2 + 2 pi rh
We know the surface area and the radius
1206.4 = 2 ( 3.14) * 8^2 + 2 * 3.14 * 8 *h
1206.4 = 401.92+50.24h
Subtract 401.92 from each side
1206.4-401.92 = 401.92-401.92+50.24h
804.48=50.24h
Divide each side by 50.24
804.48/50.24 =50.24h/50.24
16.01273885=h
Answer:
A
Step-by-step explanation:
1) Multiply 0.75 for m and -250
162.5 + 0.75m - 187.5
2) sum the therms without m
0.75m - 25
