Step-by-step explanation: when ur adding two negatives it's gonna equal a negative
Cos x = sqrt( 100 - 9) / 10
<span>= 0.9539392014</span><span>sin x = 0.3 = 3/10
</span>
2(L + W) < = P
L = 2W + 4
P 38
2(2W+4 + W) = 38
4W + 8 + 2W = 38
6W + 8 = 38
6W = 38 - 8
6W = 30
W = 30/6 = 5....the greatest possible value is 5
