Lets do it by finding the L.C.M
 
         
<span> (2, 5, 6, 9)
divide the terms by two and leave those which are not divisible

2  (1,5,6,9)

</span><span>divide the terms by 3 and leave those which are not divisible
</span>
<span>2 x 3  (1,5,2,3)
</span>
<span>divide the terms by 3 again and leave those which are not divisible
</span>
2 x <span>3 x 3  (1,5,2,1)
</span>
<span>divide the terms by two and leave those which are not divisible
</span>

2 x <span>3 x 3 x 2 (1,5,1,1)
</span>
<span>divide the terms by five and leave those which are not divisible
</span>
2 x <span>3 x 3 x 2 x 5 (1,1,1,1)
</span>So the L.C.M is :

2 x <span>3 x 3 x 2 x 5=180
</span>so correct option is D 
hope it helps

A right triangle has an area of 18 square inches.If the triangle is an isosceles triangle, what are the lengths of the legs of t
Gnom [1K]
If it is isosceles, than the legs are the same. We will call them X. The formula for the area of a triangle is 1/2 (base * height). But the base and the height are both X. So the area (18) is equal to 1/2 (x * x), or 1/2(x^2). This means that 36 = x^2. Thus, the length of each side is 6 inches. You can check this work by plugging those into the formula for area. You will find that it equals 18.
