Two trains leave the same station at the same time, but are headed in opposite directions. One train travels at 70 mph and the o

uranmaximum [27]

Let

x--------> the time in hours

y-------> the distance in miles

we know that

The speed is equal to

$Speed=\frac{distance}{time}$

in this problem

$Speed=\frac{y}{x}$

$y=(Speed)*x$

<u>Equation First Train</u>

$y1=70x$

<u>Equation Second Train</u>

$y2=80x$

$y1+y2=600\ miles$ ---------> equation $1$

Substitute the values of $y1$ and $y2$ in the equation $1$

$70x+80x=600$

Solve for x

$150x=600$

$x=4\ hours$

therefore

<u>the answer is</u>

$4\ hours$

Factor completely 8x5 2x4 4x2. Prime 2(4x5 x4 2x2) 2x(4x4 x3 2x) 2x2(4x3 x2 2).

Alecsey [184]

The complete factor of the expression $\rm 8x^5 + 2x^4 + 4x^2$ is $\rm 2x^{2} (4x^3 + x^2 + 2 )$ correct option is D.

<h3>What is a factorization?</h3>

It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.

The expression is $\rm 8x^5 + 2x^4 + 4x^2$ .

To solve the expression properly we have to take common (2x²). Then we have

$\rm 8x^5 + 2x^4 + 4x^2\\\\2x^{2} (4x^3 + x^2 + 2 )$

The factor is $\rm 2x^{2} (4x^3 + x^2 + 2 )$ .
