We are asked to find a range for x. Let's start by finding the maximum value. We know, by definition, that a side opposite a larger angle has a longer length. For example, if you think about a right triangle, the hypotenuse (the longest side) is always opposite of the right angle (the largest angle). We are given two side lengths: 23 is opposite of 42 degrees, and 21 is opposite of 3x + 15. Because 42 is opposite the longer side, 42 degrees is a larger angle than 3x + 15. We can set up the inequality and solve for x:

Now, let's look at the minimum value. We know that the angle definitely has to be larger than 0. So, we can set up that inequality and solve for x:

Now, we have our final range: -5 < x < 9

ANSWER
The volume of the dilated cube is 9375cm³.
EXPLANATION
The volume of the original cube is 75 cm³.
The scale factor for the dilation is 5.
The scale factor for volume is 5³=125
We multiply the volume of the original cube by 125 to obtain the volume of the dilated cube.
The volume of the dilated cube is
