Answer:
Where is the info so we can show you
Step-by-step explanation:
The answer is the sun because supernova turns into black holes
Area=lenght times widht
area/length=width
(4x²+12x)/(4x)=width
we can factor out the 4x
4x²+12x=4x(x+3)
so the width is x+3
Answer:
)
Step-by-step explanation:
This system we can solve by substitution method :
y=13x-1
y=9x+4
_______
y=13x-1
13x-1=9x+4 (instead y in second equation we use 13x-1 and first rewrite)
_______
y=13x-1
13x-9x=4+1 (subtract 9x and add 1 for each side)
______
y=13x-1
4x=5 (divide by 4)
_____
y=13x-1
(instead x in first eq we write 5/4)
______

Answer:
((x+3)^2)/49 - (y^2)/36 = 1
