Which expression is equivalent to this quotient? 4x^2-8x-5/4x^2-25 A. -1/5 B. 2x-1/2x-5 C. 2x-1/2x+5 D. 2x-5/2x+5

the answer is a

step-by-step explanation:

answer:   the paragraph proof is mentioned below.

step-by-step explanation:

given: in a δxwy where

such that, ∠wzx ≅ ∠yzx and zw≅zy

we have to prove that: segment zx is a perpendicular bisector of segment wy.

prove: since, zw≅zy ⇒ ∠wzy is a supplementary angle.

then, ∠wzy= 180°

⇒∠wzx + ∠yzx = 180° ( because xz divides ∠wzy into two parts)

but, ∠wzx ≅ ∠yzx ( given)

⇒∠wzy+∠wzy=180° ( by substitution)

⇒2∠wzy=180°

⇒∠wzy=90°

⇒∠wzy=∠yzx =90°

therefore, xz⊥wy where wz=zy

⇒zx is a perpendicular bisector of wy.

1. 28 over 9

2. i don't know this i'm sorry : (

3. 19, because the number of books is 95 over 4 divided by 5 over 4

4. 7 and 1 over 3 divided by 1 over 6

5. 9.5

6. $124

7. 2 over 9

8.   (−$8) ⋅ 12

9. -67.2
