4. A graph shows the solutions to be
x = -3/2, -1, 0
The root at -1 has multiplicity 2. That is, the factoring is
x(2x+3)(x +1)² = 0
5. A graph shows the real roots to be
x = -1, 2
Dividing these from the polynomial gives the quadratic
x^2 +3
which has roots
x = ±i√3
The factorization is
(x +1)(x -2)(x² +3) = 0
and the solutions are
x = -1, 2, -(√3)i, (√3)i
Answer:
I would treat it as algebra and for 2 simultaneous equations. dunno if that'll work because i haven't got pen or paper with me right now. So let adults be A and children be B
Step-by-step explanation:
So since the first number can’t have zero that means it only has 9 options.
The rest of the 6 numbers have 10 options
9*10^6
= 9,000,000
