Answer:
3:11
Step-by-step explanation:
the other ones have 7 in them
(x+3)(x+3) = x^2 -3 + 3x
x^2 + 3x + 3x + 9 = x^2 + 3x - 3
x^2 + 6x + 9 = x^2 + 3x - 3
6x + 9 = 3x - 3
3x + 9 = -3
3x = -12
x = -4
Check:
(-4+3)^2 = (-4)^2 - 3(1+4)
(-1)^2 = 16 - 3(5)
1 = 16-15
1 = 1 :)
Answer:
1/16
Step-by-step explanation:
1L = 1000 ml
2L = 2000mL
The ratio is 125/2000
Check to see if 2000 / 125 is a whole number
2000
÷
125
=
And it is. The answer is 16
125/2000 = 1/16
