The answer is A. because the side lengths of the shape doesn't change. The side lengths are still 3 and 5.
Hope this helps!

Answer:
x^2 y^2
Step-by-step explanation:
9x^2y^2/x^2y^2=9
5x^2y^2/x^2y^2=5
since 9 and 5 have no common factors except 1, x^2 y^2
mark as brainliest plz
#12. When x = 4, y = 5(4) - 1 = 20 - 1 = 19
when x = 12, y = 5(12) - 1 = 60 - 1 = 59
when x = 0, y = 5(0) - 1 = 0 - 1 = -1
when x = 0.5, y = 5(0.5) - 1 = 2.5 - 1 = 1.5
Completing the Square
2. Solve the equation by completing the square. Show your work.
x^2 – 30x = –125
Step 1: Add to both sides of the equation. (2 points)
Add 225 both sides of the equation
x^2 – 30x + 225 = –125
+ 225
x^2 - 30x + 225 = 100
Step 2: Factor the left side of the equation. Show your work. (2 points)
Hint: It is a perfect square trinomial.
x^2 - 30x + 225 = 100
Factor the left side of the equation:
(x - 15)^2 = 100
Step 3: Take the square root of both sides of the equation from Step 2. (1 point)
√(x - 15)^2 = √100
Step 4: Simplify the radical and solve for x. Show your work. (1 point)
x - 15 = + - 10
x - 15 = 10
x = 25
x - 15 = -10
x = 5
Solutions x = 25, 5
Hi, thank you for posting your question here at Brainly.
Since the hedge is surrounding the square base, the area of the base can be determined by subtracting the area of the base from the hedge.
A = pi*r^2 - (4x)^2
A = pi*(6x)^2 - (4x)^2
A = 2x^2*(3pi - 2)
I hope I was able to answer your question. Have a good day.
