Answer:
A
Step-by-step explanation:
No others make sense because you can't use multiplication in this problem and well it's hard to explain honestly lol. But I'm almost certain your answer is A
Since BD is the angle bisector of ∠ ABC,
∠ ABD = ∠ CBD --- (1)
Now, in triangles Δ ABD and Δ CBD,
BD = BD (common side)
∠ ABD = ∠ CBD from (1)
AB = BC (Given)
Hence, Δ ABD ≅ Δ CBD (SAS Rule).
Answer:
x = 6 and x = 11.
Step-by-step explanation:
sqrt(x - 2) + 8 = x
sqrt(x - 2) = x - 8
(sqrt(x - 2))^2 = (x - 8)^2
x - 2 = x^2 - 16x + 64
x^2 - 16x + 64 = x - 2
x^2 - 17x + 66 = 0
We can use the discriminant to find whether there are solutions to the equation.
b^2 - 4ac; where a = 1, b = -17, and c = 66.
(-17)^2 - 4 * 1 * 66
= 289 - 264
= 25
Since the discriminant is positive, we know there are two valid solutions to the equation.
x^2 - 17x + 66 = 0
(x - 6)(x - 11) = 0
The solutions are when x - 6 = 0 and x - 11 = 0.
x - 6 = 0
x = 6
x - 11 = 0
x = 11
Hope this helps!
Answer:
All of your choices are correct.
Step-by-step explanation:
4.50 ÷ 18 = .25 each
.25 x 4 = 1.00
.25 x 36 = 9.00
12 x .25 = 3.00
I’ll help if u attach the pic of the question:)
