Answer:

B. 3i√2.

Step-by-step explanation:

Given : √-18

To find : Which choice is equivalent to the expression below.

Solution : We have given that √-18 .

As w know that \sqrt{-1}  = i.

We can write \sqrt{18} = \sqrt{9 * 2} = \sqrt{9} * \sqrt{2}.

\sqrt{18} = 3 * \sqrt{2}.

√-18  = \sqrt{-1} *  3 * \sqrt{2}.

√-18  = i [/tex] *  3 * \sqrt{2}.

Therefore, B. 3i√2.

Hope you know that sqrt(-1) = i 

so in this case than there are sqrt(-18) = isqrt(9*2) = isqrt(3^2 *2) = 3isqrt2

so choice B. is right sure

(5+x)x=36 what is x?
lana [24]
X=4

The only way you can go about doing this is by finding the factors of 36 (1, 2, 3, 4, 6, 9, 12, 18, 36) and then seeing which pair make sense.

In this case, 9 and 4.

So, plug in the numbers so it makes sense.

(5+4)4=36

5+4=9
9*4=36

1 Camelita nuns the track at her school that is of a milelong. If she runs 4. 3 miles, how many laps did she run?​
posledela

Answer:

3 laps.

Step-by-step explanation:

Hi! I can see how this is tricky, but I was a bit confused by the 4 in "If she runs 4." It says in the problem that the track is a mile long... So if you run the track 3 times, 3 x 1 = 3.
