Hey there!
Answer:
CD = 3.
Step-by-step explanation:
Since the triangles are similar, we can set up a ratio to determine the other side-lengths:

Cross multiply:

Distribute the '6':

Combine like terms and simplify:


Therefore, the length of CD is 3.
ANSWER:
D. - 1 / 2
This is as 104 ÷ - 52 = - 1 / 2
As well as this, - 52 ÷ 26 = - 1 / 2
And this ratio applies for the other numbers in the sequence as well.
Therefore, the answer must be - 1 / 2.

Answer:
4/3
Step-by-step explanation:
find common denomerator which is 12
so times 3/4 by 3
now its 9/12 + 7/12
get 16/12
The rate of change in z at (4,9) as we change x but hold y fixed is =
3/[2sqrt(3x+2y)] put x = 4 , y = 9 = 3/[2sqrt(12+18) = 3/[2sqrt(30)] The
rate of change in z at (4,9) as we change y but hold x fixed is =
1/sqrt(3x+2y) put x = 4, y =9 = 1/sqrt(30)
