Answer:
8+3(2)
Step-by-step explanation:
8 more than indicates addition, so that makes the first part of the expression 8+.
The product of 3 and 2 indicates multiplication, since product means the result of multiplication. That finishes the expression with 3(2).
In conclusion, a numerical expression that matches the states phrase is 8+3(2). You can also do 8+3×2 too, as they equal the same thing.
It should be written in the form ax²+bx+c=0,
so you meed to move -8 to the left side
2x²+6x+8=0
the number in front of x² is a
the number in front of x is b
the number without x is c,
so a=2, b=6,c=8
Answer:
sin( -∅ )
- 1 / csc ( ∅ )
1 / csc ( -∅ )
Step-by-step explanation:
Since sin(x) is and odd function (a function where f(-a) = f(a) ).
-sin( ∅ ) = sin( -∅ )
On the other hand, we know that sin( ∅ ) = 1 / csc ( ∅ )
Another odd function, so the same as before applies.
-sin( ∅ ) = -1 / csc ( ∅ )
-sin( ∅ ) = 1 / csc ( -∅ )
