Multiply the following using the vertical multiplication method: 3x2 - 5x+1
x2 + 2x + 4
A. 3x4 – x2 + 3x2 +18x + 4
B. 3x4 + x + 10x2 + x + 4
C. 3x4 + x2 + 3x2 - 18x+4
D. 3x4 + x2 +10x2 - 18x + 4

x= 149. 24+7=31. 180-31=149

your welcome

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632

10 - 75

step-by-step explanation:

there's nothing attached so it's most likely anything in that range.

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.
