432/30 = 14.4

11 * 14.4 = 158.4

If it holds true for the entire school, 158 kids are home with the flu.

Expanding and Simplifying Triple Brackets:<br> (4x + 6) (x - 3)<br> Please help!<br> Thankyou all! X

Otrada [13]

This would only be a double bracket...

but you do
(4x+6) (x-3)
F 4x * X = 4xsquared
O 4x* -3 = -12x
I. 6xX = 6x
L. 6*-3 = -18
collect like terms:
answer= 4x2 - 6x -18
the 4x is squared :)

Find f if f′(x)=2x−3/x^4, x>0 and f(1)=2.

slavikrds [6]

$f'(x)=2x-\dfrac3{x^4}$
$\displaystyle\int f'(x)\,\mathrm dx=\int\left(2x-\frac3{x^4}\right)\,\mathrm dx$
$f(x)=x^2+\dfrac1{x^3}+C$

Given that $f(1)=2$ , we get

$2=1^2+\dfrac1{1^3}+C$
$2=2+C$
$\implies C=2$

so that

$f(x)=x^2+\dfrac1{x^3}$
