Answer:
Just as you can add or subtract the same exact quantity on both sides of an equation, you can also multiply both sides of an equation by the same quantity to write an equivalent equation. Let's look at a numeric equation, to start.
Step-by-step explanation:

When we say an angle is on a circle, we mean the vertex is on the edge of the circle. One type of angle on a circle is the inscribed angle (see Inscribed Angles in Circles). Another type of angle on a circle is one formed by a tangent and a chord.
Answer:
1. C
2.A
3.A
4.B
Step-by-step explanation:
First, lets start by getting all of the perimeters and volumes of the pools. For pool A, it has a volume of 18*9.75*4.5=789.75 cubic feet, and a perimeter of 18*2+9.75*2=55.5 feet. For pool B, it has a volume of 16*10*5=800 cubic feet, and a perimeter of 16*2+10*2=52 feet. For pool C, it has a volume of 15*12*4.5=810 cubic feet, and a perimeter of 15*2+12*2=54 feet. Therefore, for problems 1 and 2, Model C needs the largest amount of water to be filled, while model A needs the least. For problems 3 and 4, Model A uses the largest liner, while Model B uses the smallest one. Hope this helps!
