Definitely not D, because one of the x's needs to be negative, and the other should be positive so the x will end up negative when it is multiplied.
I want to say the answer is C. (-x-2i) (x-2i)
Hope this helps :)

What is the value of A when we rewrite 29^x/2 as A^x ?

lara31 [8.8K]

Is it
$\frac{{29}^{x}}{2}$
Or
$29^\frac{{x}} {2}$

Saige's spaceship traveled 588588588 kilometers (\text{km})(km)left parenthesis, start text, k, m, end text, right parenthesis i

lesantik [10]

Answer:

A is proportional

B and C are NOT proportional

Step-by-step explanation:

First, simplify 588 and 60:

588 divided by 6

60 divided by 6

= 98

Simplify them again by dividing them both by 2

= 49

Let's look at A:

441 and 45

Simplify by dividing by 9

= 49

It's pretty obvious that A is proportional because the simplified values are exactly the same.

Next, let's check B:

215 and 25

Simplify by dividing by 5

= 43

Now that its simplified you can compare

43 is smaller than 49

5 5

B is not proportional

Finally, let's check C:

649 and 110

Simplify by dividing by 11

= 51

Make 51 and 49 have the same denominator so we can compare them

10 5

51 can stay the same because 5 times 2 equals 10

49 times 2

5 times 2

= 98

Now that the denominators are the same we can compare

51 is much smaller than 98

10 10

Therefore, C is also not proportional.

Hope that helps :D
