Someone please help I suck at algebra If a = 2 and c = -6
What would ac equal?
(I don’t know what to do if two letters are together)

ac equals -12

Step-by-step explanation:

When 2 or more letters are put together, you need to multiply them.

ac=

a×c=

2×(-6)=

-12

ac= -12

-12

Step-by-step explanation:

a = 2 and c = -6

ac= a*c = 2*(-6)= -12

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.
