How do I write these questions in written form in written form? I’m supposed to use words like product, sum, quotient, dividend and so on.
9. 4(3x + 2) – 9

10. √144 – (62 –x)

11. (28 ÷ 4) – (x + 7)

12. x3 – 4y - (6 + 2)

13. (64 ÷ 8) – (x • 6)

14. 72 (4 - 15x)

15. 4(√144 + 93)–y

16. 54 + 7y – (8 + 9x)

answer: procent 54 wynosi 33,33%

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

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.
