<span>Let Rico's speed be S
Then Luis' is: 3S
</span>We then get: seventy-two over s equals seventy-two over three s plus four
216=72+12s Multiplying by LCD, 3S
216-72=12s
<span>144 = 12S
</span><span>S, or Rico's speed would be 144 over 12 or 12mph</span>
Answer: 4). A = (b1 + b2)h/2
5).
A = (b x h)/2
6). A = b x h
7). A = b x h = 65 x 50 = 3250 ft^2
8). A = (b x h)/2 = (12 x 18)/2 = 108 inches^2
9). A = (b1 + b2)h/2 = (15 + 7)4/2 = 44m^2
Answer: 6 outcomes
Step-by-step explanation: Since the first outcome is 2 and the second is 4 2 times 3 is ix since it is multiplying by 2 (2,4,6,8)
