Expand the equation.
Multiply (distribute) the first numbers of each set, outer numbers of each set, inner numbers of each set, and the last numbers of each set.
Combine like terms.
Solve the equation and simplify, if needed.
It says that there was an error with my answer, but I don't know what, so I screenshotted what I typed and attached them as 4 images below:
Well ven diagrams help you visually compare and contrast two figures. They helps you note the similarities and the differences between two items. Hope this helps!
Answer:
-4
Step-by-step explanation:
you just plug in. so, 2(6)-16
so, 2*6 is 12
12-16=-4
Answer:
The answer to your question is: the first option - 9/ ![\sqrt{80}](https://tex.z-dn.net/?f=%5Csqrt%7B80%7D)
Step-by-step explanation:
Process
cosФ = adjacent side / hypotenuse
-1/9 = adjacent side / hypotenuse
adjacent side = -1 hypotenuse = 9
c² = a² + b²
b² = c² - a²
b² = 81 - 1
b =
b = opposite side
But b is negative because we are in the third quadrant.
b = -![\sqrt{80}](https://tex.z-dn.net/?f=%5Csqrt%7B80%7D)
Finally csc Ф = hypotenuse / opposite side
csc Ф = - 9 / ![\sqrt{80}](https://tex.z-dn.net/?f=%5Csqrt%7B80%7D)
