Answer:
C) 24
Step-by-step explanation:
8; 16 24 32 40 48
12; 24 36 48 69 72
They both have the common multiple of 24 and 48 in the intermediate multiplication since 24 is half of 48 and is the smallest multiple that is the answer.
The answer is C: 16.5 square units, because the formula for the area is base times height over 2, and the height is 11; base is 3; 3 • 11 = 33; 33/2=16.5
{<em>q</em>, <em>r</em>, <em>s</em>} consists of 3 elements, so there are 2³ = 8 possible subsets.
• empty set: { }
• every possible singleton set: {<em>q</em>}, {<em>r</em>}, {<em>s</em>}
• every possible pair: {<em>q</em>, <em>r</em>}, {<em>q</em>, <em>s</em>}, {<em>r</em>, <em>s</em>}
• the set itself: {<em>q</em>, <em>r</em>, <em>s</em>}
