Unfortunately, Tashara, you have not provided enuf info from which to calculate the values of a and b. If you were to set <span>F(x)=x(x+a)(x-b) = to 0, then:
x=0,
x=-a
x=-b
but this doesn't answer your question.
Double check that you have shared all aspects of this question.</span>
The gcf of 10 and 14 is 2.
Hope this helps!
Answer:
tetrahedral
Step-by-step explanation:
According to the valence shell electron pair repulsion theory (VSEPR) the shape of a molecule is dependent on the number of electron pairs on the valence shell of the central atom in the molecule.
The predicted electron pair geometry may sometimes differ from the molecular geometry due to the presence of lone pairs and multiple bonds.
If we consider each nitrogen atom in N2 independently, we will notice that each nitrogen atom has four regions of electron density. Hence the electron pair geometry is tetrahedral.
So
represent x for number of $14 movie tickets she got
y is number of $12 movie tickets
total of 9 tickets
x+y=9
total value is 114
14x+12y=114
we have
x+y=9
14x+12y=114
solve
multiply first equation by -12 and addd to oth equesiton
-12x-12y=-108
14x+12y=114 +
2x+0y=6
2x=6
divide 2
x=3
sub back
x+y=9
3+y=9
minus 3
y=6
3 of the $14 tickets
6 of the $12 tickets
The supplementary angle of 120° is 60°.
So your answer is 60 degrees.
