fredd [130]

Answer: Jason has 7 pennies and 6 nickels.

Step-by-step explanation:

Let be "p" the number of pennies that Jason has and "n"  the number of nickels that Jason has.

Set up a system of equations:

\left \{ {p+n=13} \atop {0.01p+0.05n=0.37}} \right.

You can use the Elimination Method. Multiply the first equation by -0.01 and add both equations:

\left \{ {-0.01p-0.01n=-0.13} \atop {0.01p+0.05n=0.37 }} \right.\\................................\\0.04n=0.24\\\\n=6

Susbtitute this value into the first equation and solve for "p":

p+6=13\\\\p=13-6\\\\p=7

Answer:

<h2>V = x³ + 54x² + 936x + 5,184</h2>

Step-by-step explanation:

<h3 /><h3>If we add a value of 'x' to each side of the box, the new dimensions can be represented as</h3><h3>x + 24</h3><h3>x + 12 and </h3><h3>x + 18</h3><h3 /><h3>To find the volume of the new box, multiply all of the dimensions together</h3><h3 /><h3>V = (x + 24)(x + 12)(x + 18)    </h3><h3> Foil the first and second binomial....</h3><h3 /><h3>V = (x² + 36x + 288)(x + 18)</h3><h3>  Now multiply the two polynomials together...</h3><h3 /><h3>V = x²(x) + 36x(x) + 288x + x²(18) + 36x(18) + 288(18)</h3><h3 /><h3>V = x³ + 36x² + 288x + 18x² + 648x + 5,184</h3><h3 /><h3>which simplifies to</h3><h3 /><h3>V = x³ + 54x² + 936x + 5,184     where x represents the increase in inches</h3>
