Answer:

x = 21

Step-by-step explanation:

x + 15 - 15 = 21

+ 15 and - 15 cancel out

So x = 21

Let's solve the longer way

x + 15 - 15 = 21

x + 15 = 21 + 15 . (adding 15 to both sides)

x = 21 (Subtracting 15 from both sides)

If my answer is incorrect, pls correct me!

Tìm căn bậc hai của số phức z=1+i√3

Anni [7]

Write z in polar form:

z = 1 + √3 i = 2 exp(i π/3)

Taking the square root gives two possible complex numbers,

√z = √2 exp(i (π/3 + 2kπ)/2)

with k = 0 and k = 1, so that

√z = √2 exp(i π/6) = √(3/2) + √(1/2) i

and

√z = √2 exp(i 7π/6) = -√(3/2) - √(1/2) i

Animal shelter house ratio catch a dog that is 9:7. If the shelter only as his dogs and cats what is the ratio of dogs total ani

Molodets [167]

Answer:

The ratio of dogs to animals $\frac{9}{16}$ .

Step-by-step explanation:

If the shelter captures 9 dogs they also catch 7 cats.

So,

the total number of Animals = Total number of Dogs + Total number of Cats

= $9+7$

= $16$

Therefore,

The ratio of dogs to animals = Number of Dogs / Total number of animals

= $\frac{9}{16}$

I’m not sure about the answer but I know it wouldn’t be D because it’s positive. I think it maybe B though. Hope this helps!
