To solve, divide the amount of cells in the human body by the population of north Carolina:

$\frac{3*10^1^3}{1*10^7} = \frac{30000000000000}{10000000} = 3000000 = 3*10^6$

Hunter and Brian are creating a poster for a project and they need to combine two different size boards to create their project.

Answer:

<em>The maximum area of the second board must be $(5x^2+3x-6)$ square inches.</em>

Step-by-step explanation:

The total area of two different size boards cannot exceed $(7x^2-6x+2)$ square inches.

The area of one board is $(2x^2-9x+8)$ square inches.

Suppose, the area of the second board is $y$ square inches.

That means......

$y+(2x^2-9x+8)\leq 7x^2-6x+2\\ \\ y\leq (7x^2-6x+2)-(2x^2-9x+8)\\ \\y \leq 7x^2-6x+2-2x^2+9x-8\\ \\ y\leq 5x^2+3x-6$

So, the maximum area of the second board must be $(5x^2+3x-6)$ square inches.
