A rectangle has a length of x and a width of 5x^3+4-x^2. What is the polynomial that models the perimeter of the rectangle

sveticcg [70]

Answer:

$L= x$

And the width for this case is:

$W= 5x^3 +4 -x^2$

And we know that the perimeter is given by:

$P= 2L +2W$

And replacing we got:

$P(x) = 2x +2(5x^3 +4 -x^2)= 2x +10x^3 +8 -2x^2$

And symplifying we got:

$P(x)= 10x^3 -2x^2 +2x+8$

Step-by-step explanation:

Solve and show work 7^(4x-3)=22

Sophie [7]

$7^{4x-3}=22$
$\log_77^{4x-3}=\log_722$
$(4x-3)\log_77=\log_722$
$4x-3=\log_722$
$4x=3+\log_722$
$x=\dfrac{3+\log_722}4$
