11. The steps Irena took to simplify an expression are shown below. What should Irena change in order to simplify the expression correctly?
12(48 + 24) = 12 x 48 + 24
576 + 24
= 600
c.
a. Multiply 48 and 24 by 12.
b. Add 12 to(48 + 24)
Divide 48 and 24 by 12.
d. Multiply 24 by (48 + 12)

17   x 256=4352

sorry if this is wrong, i'm new.

step-by-step explanation:

positive

step-by-step explanation:

the quadrant is facing upwards

the correct answers i think are b. and d.

give me brainliest if it 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.
