Answer:
9
Step-by-step explanation:
(-9)^1/3 * (-81)^1/3
We can rewrite -81 as 9 * -9
So it can be rewritten as:
(-9)^1/3 * (9*-9)^1/3
Since they are all raised to the 1/3, we can combine the bases:
(-9*9*-9)^1/3 =
(9*9*9)^1/3, because the two negatives turn into a positive:
So this is basically:
(9^3)^1/3 = 9^1 = 9
Answer:
A, D , and E
Step-by-step explanation:
We have that:


is the image of CD after a dilation of scale factor n.
We use the relation between the image length and object length:

Option A
If n=3/2, then

This is true.
Option B
If n=4, then

This is false.
Option C
If n=8, then

This too is false.
Option D
If n=2, then

This is true
Option E
If n=3/4, then


This is also true.
Hello!
I believe that the answer would be 40²
I hope this helps!
Answer:
x=−2−√5 or x=−2+√5
Step-by-step explanation:
-5x2 - 20x + 35 = 30
Answer = x=−2−√5 or x=−2+√5
Divide both sides by 2.
