Answer:
It's a.
Step-by-step explanation:
(a - 2b)^2 + 8ab
= a^2 - 4ab + 4b^2 + 8ab
= a^2 + 4ab + 4b^2.
((a + 2b)^2 = a^2 + 4ab + 4b^2.
The answer is D. They both had the same proportion.
Hope this helps!!!
Answer:
x = 110°
Step-by-step explanation:
Given that AB = AD then Δ ABD is isosceles and the base angles are congruent, that is
∠ ABD = ∠ ADB = 35°
The sum of the 3 angles in the triangle = 180°, that is
x + 35° + 35° = 180°
x + 70° = 180° ( subtract 70° from both sides )
x = 110°
