Answer:
look below
Step-by-step explanation:
i dont know what that +... thing is
but when youre adding the negatives youre really just adding that number so this is just
48+45+42+81+84
45+42 is 87
now we have
48 + 87 + 81 + 84
87 + 81 is 168
48 + 84 is 132
now we have
168 + 132 and that is exactly 300
again dont know what the ... is so cant help you there
The first answer is figure B
the second is figure A because all angles are equal
the third is Hex regular

merry christmas my apologize for being to vague with my last answer
Because LP squared plus PM squared must equal LM therefore LP cannot be less.
Answer:
W=v/h.
Step-by-step explanation:
V=1wh
divide both side by 1h
v/1h=w
w=v/h
1) A quadratic will have no real roots when its discriminant is negative
Dividing by 4,
We have a positive coefficient on k^2 so this parabola is a CUP (concave up positive) so has a minimum at the vertex. If the vertex y value is less than zero, the inequality will be true in the range between the zeros.
That's true for
2) We look for the meet of the line and the parabola:
For two intersections we need a positive discriminant:
That's means two negative or two positive, so
or
