Answer:
B.
Step-by-step explanation:
B. Because the others have exponents whose denominators are even so the results of , for example x^1/2, if x is negative is not defined.
For example:
For A, when x is -4, (-4)^1/2 is not real.
For B, when x = -4, (2*-4)^ 1/3 = -8^(1/3) = = -2.

Answer:
Step-by-step explanation:
Given
- A is between C and T
- CA =4x + 6
- AT =7x-6
- CT =132
As per segment addition postulate:
- CT = CA + AT
- 4x + 6 + 7x - 6 = 132
- 11x = 132
- x = 132/11
- x = 12
Answer:
0.8
I hope this helped, have a great day!
Answer:
r = 7
Step-by-step explanation:
Use the distributive property by multipling the -8 to the 2r and the -8, do the same thing on the other side with the -3.
Afterwards, combine like terms by adding 64 and 6.
Next, add 3r to the left side, I usually choose the number with the variable (the letter) that looks like it will be easier to subtract. This leaves only 21 on the right side.
Next subtract 70 from both sides
Divide -13 by both sides
You should get the answer of r=7
