Pls help me! 19 and 20.

Murljashka [212]

Answer:

See below ↓

Step-by-step explanation:

19.

$\frac{x-1}{2} - \frac{x-3}{5} - \frac{x-7}{10} + \frac{x-2}{5}$
$\frac{5(x-1)-2(x-3)-(x-7)+2(x-2)}{10}$
$\frac{5x-5-2x+6-x+7+2x-4}{10}$
$\frac{4x+4}{10}$
$\frac{2x+2}{5}$

20.

$\frac{2x+3}{2x} + \frac{x+3}{4x} - \frac{18x+6}{8x^{2} }$
$\frac{4x(2x+3)+2x(x+3)-(18x+6)}{8x^{2} }$
$\frac{8x^{2} +12x+2x^{2} +6x-18x-6}{8x^{2} }$
$\frac{10x^{2}-6}{8x^{2} }$
$\frac{5x^{2}-3}{4x^{2} }$

Can someone help? It’s about 2 column proofs

Gwar [14]

Step-by-step explanation:

1. AB = BC (B is the midpoint of AC)

2. DE = EF (E is the midpoint of DF)

3. EB is common

4. ∠ABE = ∠CBE; ∠BED = ∠BEF (EB⊥AC, EB⊥DF)

5. ΔDEB ≅ ΔFEB (RHS)

6. DB = FB (corresponding ∠s of ≅ Δs)

7. ∠EFB = ∠CBF; ∠EDB = ∠ABD (alternate interior angles, AC║DF)

8. ΔABD ≅ ΔCBF (SAS)
