9+3=12
30+20=50
300+100=400
Then add.
12+50+400=462
<span>So 339+123=462</span>
Answer: She is correct because each ratio is equivalent to 5:1, except for the last one, which is 1:5

25/5 = 5:1
10/50 = 1:5
The answer is
C = 4 ÷ 1/5

Answer:
y≤x²+4x-1.
Step-by-step explanation:
1) to define the equation of the given graph; it is y=x²+4x-1 (its vertex is (-2;-5));
2) to define inequation accorging to the given graph (the area outside of the parabola means ≤).
