Answer:

a is write, b is wrong

Step-by-step explanation:

b) difference is subtraction!

The question asks "the sine of a difference of two real numbers is not necessarily equal to the difference of the sines

So the first part is "the sine of a difference of two real numbers" would be writtten as : sin (x-y)

The second part, the difference of the sines,  would be: sinx - siny

Help me with a question?
kherson [118]

Answer:

B

Step-by-step explanation:

y = mx + b

The slope is m.

If it was anything other than 0, the line would have an x in it. The line does not have an x associated with it.

The equation of the line is y = 1

The slope must be 0.

Someone please help me I will give brain list!!!!!!!
wel
The answer is 1,632. You multiply 16 by 17 then by 12 to get 3,264. But since it is a triangle, which is half of a rectangle, you divide by 2, and you get 1,632. Hope this helps!
