Answer:
She should aim 6 feet down the wall
Explanation:
The diagram attached sketches the situtation.
Since the angle with which the ball hits the wall is the same with which it bounces, angle β is the same for the two shown triangles.
Then, since both are right triangles, then all the angles are congruent and the triangles are similar. Hence, you can equal the ratios of the sides, to make an equation:
x/4 = y/2 ⇒ x = 2y
You have other equation:
x+ y = 18
Substitute
2y + y = 18
3y = 18
y = 18/3
y = 6 ← this is the distance down the wall where the ball should hit
x = 2(6) = 12
Then, she should aim 6 feet down the wall.

Step-by-step explanation:
= 3 +
[3 + ] = 54 ↷
² + 3 - 54 ↷
[x - 6][x + 9] = 0

We want this expression because when we talk about dimensions, we want NON-NEGATIVE numbers. The other expression gives us a solution of <em>-</em><em>9</em><em> </em><em>=</em><em> </em><em>x</em><em>,</em><em> </em>and we do not want that; this one gives us <em>6</em><em> </em><em>=</em><em> </em><em>x,</em><em> </em>and THIS is what we are looking for.
