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

shepuryov [24]

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.

Answer:

D = 59t

P = 42t

5 hours after noon, darmian is 17 miles closer to the stadium than paisley

Step-by-step explanation:

At noon, Damian is 383 miles away from the stadium and paisley is 315 miles away from the stadium.

Now, we are told that damians speed is 59 mph while paisley's speed is 42 mph.

At t hours after noon, their distance covered will be;

Damian; D = 59t

Paisley; P = 42t

This is because distance = speed × time

Now, 5 hours after noon, their respective distance covered will be;

D(5) = 59 × 5 = 295 miles

P(5) = 42 × 5 = 210 miles

This means that;

distance of Damian from the stadium is; 383 - 295 = 88 miles

Distance of paisley from the stadium is;

315 - 210 = 105 miles

Difference in their distances to the stadium = 105 - 88 = 17 miles

Thus, 5 hours after noon, darmian is 17 miles closer to the stadium than paisley
