Answer:
Step-by-step explanation:
3.AE = CE E is the midpoint of AC
4. ∠AEB = ∠CED Vertically opposite angles are equal
5. ΔAEB = ΔCED ASA congruence
The derivative of x^3 is 3x^2.... is that what you were looking for?
247 is the correct answer!
Answer: y=8
Step-by-step explanation:
Since DF is bisected, it means but in half. This means DU and UF are equal in length. We can set them equal to each other to find y.
2y=16 [divide both sides by 2]
y=8
Answer:
x = 1 ±2sqrt(5)
Step-by-step explanation:
2x^2-4x-9=29
Add 9 to each each side
2x^2-4x-9+9=29+9
2x^2-4x=38
Divide by 2
2/2x^2-4/2x=38/8
x^2 -2x =19
Complete the square
x^2 -2x + (-2/2)^2 = 19 +(-2/2)^2
x^2 -2x +1 = 19+1
(x-1)^1=2 = 20
Take the square root of each side
sqrt((x-1)^2) = ±sqrt(20)
x-1 = ±sqrt(20)
Add 1 to each side
x-1+1 = 1 ±sqrt(20)
x = 1 ±sqrt(20)
Simplifying the square root of 20
x = 1 ±sqrt(4)sqrt(5)
x = 1 ±2sqrt(5)
