Answer:
-9
Step-by-step explanation:
Simplify the following:
-6×(-2)/4 (-3)
-6×(-2)/4 (-3) = (-6 (-2) (-3))/4:
(-6 (-2) (-3))/4
The gcd of -2 and 4 is 2, so (-6 (-2) (-3))/4 = (-6 (2 (-1)) (-3))/(2×2) = 2/2×(-6 (-1) (-3))/2 = (-6 (-1) (-3))/2:
(-6-1 (-3))/2
(-6)/2 = (2 (-3))/2 = -3:
--3 (-3)
-3 (-1) = 3:
3 (-3)
3 (-3) = -9:
Answer: -9

Answer:
7y
Step-by-step explanation:
7yg^0 is equal to 7y(1). Anything to the power of 0 is equal to 1. This means that the expression will be equal to 7y times 1 or 7y.

Answer:
Adnan is incorrect because cosx and sin(90 - x) are always equivalent in any right triangle ⇒ first answer
Step-by-step explanation:
In any right triangle there are two acute angles sum of them is 90°
∴ If one of them x°, then the other is (90 - x)°
∵ cos x = adjacent/hypotenuse
∵ sin(90 - x) = opposite/hypotenuse
∵ The opposite of ∠(90 - x) is the adjacent of ∠x
∴ cosx = sin(90 - x)
