1. a=h(b+c)
2. distribute the h:
a=hb+hc
3. move the 'hb' to the left:
a - hb = hc
4. subtract the a from both sides:
-hb = hc - a
5. divide both sides by -h to isolate b:
b = -hc+a/h
You multiply six by six and then get 36 and divide 36 to 4 and you would get 9 so put 9 in the 6 6's that you got.
Answer:
224
Step-by-step explanation:
7x^2 y
Let x =4 and y=2
7(4)^2 (2)
7*16*2
224
B
Step-by-step explanation:
Answer:
The number of different playlists possible with order important = 1.9996 × 10¹³ ways = 2.00 × 10¹³ ways
Step-by-step explanation:
Selection problems in which the order matters are permutation problems.
So, the choices are 4 reggae songs from 11
4 pop songs from 12
4 rock songs from 23
number of ways = ¹¹P₄ × ¹²P₄ × ²³P₄ = 7920 × 11880 × 212520 = 19,995,921,792,000 = 1.9996 × 10¹³ ways
