You first have to find the length of each side.
AB=4
BC=4
CD=4
AD=4
Since this is a quadrilateral, two sides will have the same length, in this case, they all do so you can pick any two sides.
4(4)=16.
Step-by-step explanation:
Flipping a tails and rolling at least a tail are 2 independent events: they don't affect each other. So, to get the probability of both happening, we just need to multiply the probability of one by the probability of the other. he probability of rolling at least a 2 is 5/6.
<span>multiply the first equation by 5 and 2nd by -7 and you get
35x-30y=-5
-35x+28y=-7
now you can cancel out the x's and you get
-2y=-12
so
y=6
now you can just plug y=6 into one of the original equations and you will see that x turns out to be 5
Hope thats okay</span>
If you take 2/5 minus 8/10 the final results would be -2/5 and it equals -0.4.
