Answer:

Lets start off by saying that a square root is basically that number multiplied by itself.

Ex: the square root of 9 is 3 because 3 x 3 is 9

the square root of 4 is 2 because 2 x 2 is 4

the square root of 25 is 5 because 5 x 5 is 25

and so on.

so 9 x 4 = 36

the square root of 36 is 6 because 6 x 6 is 36.

the number 6 isn’t on this list here.

your option would be B) because the square root is 9 is 3 and the square root of 4 is 2.

3 x 2 = 6

B is equivalent to the equation in the problem.

So your correct answer is B. Please hit the thx button and mark me brainliest if this helped :)

How do you express sin x + cos x in terms of sine only?

frez [133]

Answer:

$\sin x + \sqrt{1-\sin^2x}$

Step-by-step explanation:

Given: sin x + cos x

To change the given trigonometry expression in term of sine only.

Trigonometry identity:-

$\sin^2x+\cos^2x=1$
$\cos x=\sqrt{1-\sin^2x}$

Expression: $\sin x+\cos x$

We get rid of cos x from expression and write as sine form.

Expression: $\sin x + \sqrt{1-\sin^2x}$ $\because \cos x=\sqrt{1-\sin^2x}$

Hence, The final expression is only sine function.
