Hannah is giving her sister a softball for her birthday, and wants to put it in a cubic gift box to preserve the surprise. She w
1 answer:
Answer:
B. E(s) = s^3 - 29.
Step-by-step explanation:
The amount of empty space inside the cubic box is equal to the volume of the box minus the volume of the softball.
If the side length of the cubic box is , and the volume of the softball is
, then the amount of empty space
inside is
,
where is the volume of the cubic box.
Since it matches the equation we got above, choice B stands correct.

<h3>Answer: Choice D. 
</h3>
The red angle markers show those two angles are congruent. That's one "A" of "ASA". The S refers to a congruent pair of sides. We don't have any tickmarks to indicate congruent pairs; however, we do know that QR = QR is a shared side that overlaps (reflexive theorem). So this is the "S" in "ASA".
The thing missing is the angle Q of the top triangle, and also of the bottom triangle as well. If we know those two angles are congruent, then we have enough info to use ASA. More specifically, if we know that , then we can use ASA.
One thing to notice is that the other answer choices involve side lengths and not angles. This implies that if A, B or C were one of the answers, then we would have something like SAS or SSS. But instead we want ASA. So we can immediately rule choices A,B, and C out.
