Answer:

As the picture shows, we have

V = (x+5)(x-2)x =30x

<=> x(x^2+3x-10) =30x

<=> x^3 + 3x^2-10x-30x = 0(*)

<=> x^3 +3x^2 -40x = 0

<=> x(x-5)(x+8) =0

Solve for (*), there are 3 solution :

5,

0(invalid),

-8(invalid)

=> 3 dimensions of rectangular box: 5, 3, 10

Ymorist [56]

Answer:

\£465.31

Step-by-step explanation:

we know that

The insurance company reduces the price by 2.1%

Remember that

The actual cost of £475.29 a year represent the 100%

so

100\%-2.1\%=97.9\%=97.9/100=0.979

To find out the new insurance cost, multiply the original cost by the factor 0.979

\£475.29(0.979)=\£465.31
