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.
Answer:
Step-by-step explanation:
The triangle on the right is shorter than the triangle on the left, plus you an clearly see that we do not have enough information as proof that we cannot use this theorem.

Answer:
Step-by-step explanation:
This is a direct instance of multiplying like term.
-Given the terms X and 1/2 X, there product can be obtained as;
-A number of term multiplied by itself is that number/term squared.
Hence, the product of X by 1/2X is
Less than because it is bigger when you make it into an improper fraction
