It could be written like 400 or four hundred.
The volume of the metal box if the box was completely solid (V1), is:
V1=(12 inches)³
V1=1728 inches³
As there are 3 inches of metal on both sides, the widht if the metal box was not completely solid, is:
W=12 inches-(3 inchesx2)
W=6 inches
Then, the volumen of the no solid metal box is:
V2=(6 inches)³
V2= 216 inches³
Therefore, the volume of metal needed to smelt the cubical metal box, is:
V3=V1-V2
V3=1728 inches³-216 inches³
V3=1512 inches³
Answer:

Step-by-step explanation:
C.


D.


To find the length of a side of a square fins the square root of the area.
Area = 200 cm^2
Side = √200
Side = 10√2 (Exact length)
or 14.142 cm's ( round the decimal answer as needed.)
Answer: y ≥ -2 Interval Notation: [-2, ∞)
<u>Step-by-step explanation:</u>
If the domain is x ≥ 0, then plug x=0 into the given equation to find the y ≥ value.
Range: y ≥ 2(0) - 2
y ≥ 0 - 2
y ≥ -2
