$s(x)=x-7\\t(x)=4x^2+3\\\\(t\times s)(x)=t(x)\times s(x)\\\\\text{Substitute:}\\\\(t\times s)(x)=(4x^2+3)(x-7)\\\\\text{use FOIL:}\ (a+b)(c+d)=ac+ad+bc+bd\\\\(t\times s)(x)=(4x^2)(x)+(4x^2)(-7)+(3)(x)+(3)(-7)\\\\=4x^3-28x^2+3x-21$

Use proportion to find the answer.

prisoha [69]

<u>Answer</u>

$\boxed {64}$

<u>Detailed Explanation </u>

Let's set up a proportion.

$\frac{3}{4.8} = \frac{40}{x}$

Now that we have set up a proportion we would need to cross multiply.

3*x=3x

40*4.8= 192

Solve for x

$3x=192$

$\frac{192}{3} = 64$

Therefore, the answer would be 64.
