Answer:

f(x) = ( x + 1 ) ( x - 8 )

Step-by-step explanation:

We have to find a polynomial equation that has double zeros at x = - 1 and at x = 8

Therefore, the polynomial has only two roots and it will be a quadratic polynomial and it has factors ( x + 1 ) and ( x - 8 )

So, the polynomial is y = f(x) = ( x + 1 ) ( x - 8 ) (Answer)

£140 is divided between Angad, Nick & June so that Angad gets twice as much as Nick, and Nick gets three times as much as Ju
kramer

Answer:

84

Step-by-step explanation:

Let's say Nick gets amount N, Angad amount A, and June amount J.

Here's what we know:

A+N+J=140

A=2*N

N=3*J.

Let's plug these values in.

N=3*J, so A+N+J=140 can now be A+3*J+J=140.

A=2*N, and N=3*J, so A=2*3*J=6*J. Then, A+3*J+J=140 is now 6*J+3*J+J=140, so 10*J=140 and J=14. N = 3*J=42 and A=2*N=84. Checking this, 14+42+84=140, so we are good to go!
