You can't exactly get the trigonometric functions using a point unless it's a vector,
so tanx = -8/-6 = 4/3 and from it we can get the other functions
sinx = -4/5
cosx = -3/5
secx = -5/3
cscx = -5/4
cotx = 3/4
D, because the sum is no more than 28 so it could be equal or less than.

Answer: 6x+9c+4
Step-by-step explanation: (8 + 6x) + (-4 + 9c)
8+6x-4+9c
6x+9c+8-4
6x+9c+4
since there is always a decimal at the end of every value so :
= 262144.0
you move the decimal backwards if there is no decimal between the value. you place the decimal after the 1st digit, you will also count the digits you have passed :
= 2.62144 X 10^5
you passed 5 values so you put 5 in exponent form.
