Answer:
D) b = 
Step-by-step explanation:
First, move all the terms that do not include b to the left side with S:
S = 2ab + 2bc + 2ac
S - 2ac = 2ab + 2bc
Now, factor out 2b from the right side:
S - 2ac = 2b(a + c)
Divide both sides by 2(a + c):
b = 
Finally, multiply out the denominator:
b =
Answer:

The exact distance she drove was 236.39 miles

Answer:
B
Step-by-step explanation:
The trick you need to employ is that when the rock hits the ground, the timer stops. So h must be taken as 0.
0 = - 16t^2 + 255 Set up the equation
- 255 = - 16t^2 Divide by -16
15.9375 = t^2 Switch
t^2 = 15.9375 Take the square root of both sides.
sqrt(t^2) = sqrt(15.9375)
t = 3.992 seconds
The closest answer is B
The leaf of the number 392 would be. 2 cause there can be a lot of numbers that begin 39. Example:-
Plot 389, 392, 395, 351, 408 on a stem-and-leaf plot:-
Stem| Leaf
35 |1
38 |9
39 | 2 5
40 | 8
