Hello There!
Dividing a fraction is the same thing as multiplying by its reciprocal.
This means that 
÷ 
is the same as multiplying by 
.
So basically when you divide you leave the first fraction alone but the second fraction in this case, 5/12 you would flip the number on top and the number on bottom to 12/5.

Answer:
m∠ABD = 20°
Step-by-step explanation:
The bisector makes angles ABD and BDC congruent, so ...
7x -1 = 4x +8
3x = 9 . . . . . . add 1-4x to both sides
x = 3
m∠ABD = (7x-1)° = (7·3 -1)°
m∠ABD = 20°
Answer:
2,4, and 8.
Step-by-step explanation:
If the population has a doubling time of 25 years, that means that in 25 years the population will double. So for 25 years, the factor will be 2. For 50 years, the factor would be 2x2, which is 4. For 100 years, it is 4x2 which is a scale factor of 8.
General formula of the parabola in vertex form is
f(x) =(x-h)² +k, where (h,k) is a vertex of the parabola.
f(x) = (x + 5)²- 28
h= -5, k = -28,
so (-5, -28) is a vertex of the given parabola.
Answer is A.
