Answer:

Area of living room

= 20(x+5)

= 20x +100

Area of dining room= 20x

Total area

= 20x +100 +20x

= 40x +100

Total perimeter (after wall is removed)

= 2(20) + 2( x+x+5)

= 40 + 2(2x+5)

= 40 +4x +10 (expand)

= 4x +50 (simplify)

Step-by-step explanation:

Area of rectangle= length × breadth

Step-by-step explanation:

3/4 +1/6=11/12 (to add/subtract fractions you need to find LCD and then combine)

after you get 11/12 subtract it from 2/3= 1/4 (to add/subtract fractions you need to find LCD and then combine)

Answer:

F. 30  G. 8

Step-by-step explanation:

F. 9 / 9 + 6 = 18 / BC

9 + 6 = 15

9 / 15 = 18 / BC

9 x 2 = 18

15 x 2 = 30

G. 9 / 6 = 12 / EC

9/6 reduces to 3/2

3/2 = 12/EC

3 x 4 = 12

2 x 4 = 8

Question in pic. Plz open the pic for the question ..corect gets branliest
mel-nik [20]
<h2><u>Answer with explanation</u>:</h2>

Given: In Δ ABC and ΔAEC,

AB=BC and AD=CD

i) In ΔADB and CBD, we have

AD = DC        [given]

AB=BC           [given]

DB= DB           [given]

⇒ ΔADB ≅ΔCDB   [By SSS congruence rule]

⇒ ∠ADB ≅∠CDB       ...(i)           [Corresponding parts of congruent triangles are congruent]

Since AC is a straight line,

∠ADB+∠CDB = 180°   [Linear pair]

⇒∠ADB+∠ADB=180°   [from (i)]

⇒2 ∠ADB=180°  

⇒∠ADB=90°  =∠CDB

Also ∠ADB+∠ADE=180°   [Linear pair]

⇒∠ADE=180°-∠ADB  = 180°-90°

⇒∠ADE=90°, i.e. ∠ADE is a right triangle.

Similarly, ∠CDB+∠CDE=180°

⇒∠CDE=90°

ii) Now, in ΔADE and CDE

AD= CD   [given]

ED=ED   [Common]

∠ADE= ∠CDE = 90°

⇒ΔADE ≅ CDE   [By SAS congruence rule ]

⇒AE=EC   [Corresponding parts of congruent triangles are congruent]

Hence proved.
