Answer:
B. 37 units
Step-by-step explanation:
DE = 4x + 1
AB = 11x - 25
DE is a midsegment of the ∆ABC
Therefore:
DE = ½(AB) => Triangle Midsegment Theorem
4x + 1 = ½(11x - 25)
2(4x + 1) = 11x - 25
8x + 2 = 11x - 25
Collect like terms
8x - 11x = -2 - 25
-3x = -27
-3x/-3 = -27/-3
x = 9
✔️DE = 4x + 1
Plug in the value of x
DE = 4(9) + 1 = 36 + 1
DE = 37
Answer:
i cant quite see the questin can you like take a closer picture
Answer:
Correct option is
B
(1−3a−3b)(1+a+b)
1−2a−2b−3(a+b)
2
=−3(a+b)
2
−2(a+b)+1
=−3(a+b)
2
−3(a+b)+(a+b)+1
=−3(a+b)((a+b)+1)+((a+b)+1)
=((a+b)+1)(1−3(a+b))
=(a+b+1)(1−3a−3b)
Answer:
Step-by-step explanation:
Answer:
Step-by-step explanation:
The angles ∠2 and 146° are corresponding angles as per drawing
<u>Since corresponding angles are equal, we have:</u>
m∠2 = 13x + 3 and m∠2 = 146°
- ⇒ 13x + 3 = 146°
- ⇒ 13x = 143°
- ⇒ x = 143°/13
- ⇒ x = 11°
