Answer:

x > -3.

Step-by-step explanation:

The circle on the -3 is clear. That means that -3 is not included in the inequality. The shading is to the right so the answer is x > -3 ( x is greater than -3).

Answer:

x > -3

the third option

Step-by-step explanation:

the circle is not filled in so we can first rule out the 2nd and last option. then since the arrow is pointing towards the positive side we can say x is more than -3

So hmm notice the picture below

one is 7x5x1.75 the volume of a rectangular prism is V = length * width * height

so 7*5*1.75 gives us 61.25 ft³

the second one, is larger by some width and length we dunno, but we know that it required that 61.25 plus an extra 17.5 to fill it up, so its volume is 61.25 + 17.5 or 78.75

the height is the same... so $\bf V=l\cdot w\cdot h\qquad 
\begin{cases}
l=length\\
w=width\\
h=height\\ --------\\
h=1.75\\
V=78.75
\end{cases}\implies 78.75=lw\cdot 1.75
\\\\\\
\cfrac{78.75}{1.75}=lw\implies 45=lw$

so.. if you factor 45, to two factors, one will be the length, the other the width
