18 ÷ 3 is 6, which means that Daniel is 6, and there is a 12 year gap between Steve and Daniel.
12 x 2 is 24, so therefore when Steve is 24, Daniel will be 12, so Steve is twice as old as Daniel:)
We need the cross product of the two vectors.
a x b
=<2,-2,-3> x <3,2,2>
=
i j k
2 -2 -3
3 2 2
=<-4+6, -(4+9), 4+6>
=<2,-13,10>
The second vector is obtained by reversing the direction, namely <-2,13,-10>
Thus the two vectors are <2,-13,10> and <-2,13,-10>.

Answer:
The equation showing this situation is 
Step-by-step explanation:
Given : A quadratic equation of the form 
has one real number solution.
To find : Which could be the equation?
Solution :
A quadratic equation in form 
has a solution 
called a quadratic formula in which the roots are one real,two real or no real is determine by discriminant factor.
Discriminant is defined as to determine the number of roots in a quadratic equitation has following rules :
1) If 
there are two real roots.
2) If there are one real roots.
3) If 
there are no real roots.
According to question,
A quadratic equation of the form has one real number solution.
So, The equation showing this situation is
7/10 of the degrees of a circle is 252 . I dont know the second part of the question sorry.
