Answer:
true
Step-by-step explanation:
1/2 (sin(x+y)+sin(x-y))
= 1/2 (sin x cos Y + cos x sin y + sin x cos y - cos x sin y)
= 1/2 * 2 sin x cos y
= sin x cos y
The expression is true.
In the given quadrilateral ABCD,
(Sum of interior angles of a quadrilateral is 360 degrees)
(Substitution Property)
(Addition Property of Equality)
Answer: 20025 gallons per hour
89 times 60= 5340 cups in one minute
5340 times 60= 320,400 cups in one hour
Convert 320,400 cups into gallons and you will get 20025.
Not positive if this is correct but it’s better than nothing lol.
We just combine the terms, like this:
-8y = -12
The answer is: y = 1.5 or 3/2.
Hope this helped! c:
