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.

Which statement(s) about the graph are correct? Select ALL that apply.
hoa [83]

Answer: B and D are correct.

Step-by-step explanation:

A is wrong because they will eventually intersect (the arrows show that the line continues on).

B is correct; that is where they will intersect.

C is wrong because they only intersect at one point, and that's where the solution is.

D is correct because they intersect once and have only one solution.
