Answer: 0
Step-by-step explanation: -8+8=0
For this case we have the following equation:
We apply distributive property on the left side of the equation:
We add similar terms taking into account that, equal signs are added and the same sign is placed:
we subtract 6x on both sides of the equation:
We add 18 to both sides of the equation:
We divide by 8 on both sides of the equation:
Finally, the order of the steps is:
ANswer:
<span>x=theta
so we know that tanx = sinx/cosx
therefore is tanx = 4/3 and sinx = -4/5
we can set up an equation to find cosx
so 4/3 = (-4/5)/cosx
we can multiply x to have cosx(4/3)=-4/5
we can then divide 4/3 over so we have
cosx = (-4/5)/(4/3)
therefore, cos x = -3/5

there is the answer
i hope this help
Answer:
Step-by-step explanation:
-2x²-3x+8=0
disc.=b²-4ac=(-3)²-4(-2)(8)=9+64=73>0
it has two real irrational solutions.
