Answer:
(b - c)(a - d)
Step-by-step explanation:
Given
a(b - c) + d(c - b) ← factor out - 1
= a(b - c) - d(b - c) ← factor out (b - c) from each term
= (b - c)(a - d)
The volume-to-surface-area ratio would be better for an ice cube is the highest possible one.
<h3>How to explain the volume?</h3>
When you put ice into your drink, the goal is to have the ice chill your drink. This takes time. Therefore, you would want the ice to slowly melt and cool the drink for as long as you can.
You would want to have the highest possible volume to surface area ratio in an ice cube. If your ice cube is mostly surface area with less volume, it will melt quickly and water down your drink. If your ice cube has a higher ratio of volume to the surface area, it will stay solid longer and chill your drink longer.

The rates are equivalent because both of them do 30 jumping jacks a minute.
The measure of the angle 2 is 133° and the measure of the angle 3 is 47°.
<h3>Classification Angles</h3>
They are a lot of classifications for angles like: complementary angles, supplementary angles, right angles, and others. See below:
- complementary angles - two angles whose the sum is equal to 90°.
- supplementary angles - two angles whose the sum is equal to 180°.
- right angles - angles whose the measure is 90°.
From the figure, it is possible to see that:
- the angles 1 and 3 are supplementary angles
- the angles 2 and 3 are supplementary angles
Therefore, if angle1 is 133°, you have:
angle_1 + angle_3 = 180
133 + angle_3 = 180
angle_3=180-133
angle_3=47°
If angle3 is 47°, you have:
angle_3 + angle_2 = 180
47+ angle_2 = 180
angle_2=180-47
angle_2=133°
