The simplification of the polynomial expression will give 3x² - 20x + 8.

<h3>How to illustrate the polynomial?</h3>

The polynomial expression is given as:

(5x² + 13x4) (17x² + 7x - 19) + (5x-7)(3x + 1)

= 5x² + 13x - 4 - 17x² - 7x + 19 + 15x² + 5x - 21x - 7

Then collect like terms

= 5x² + 15x² - 17x² + (13x - 7x + 5x - 21x) - 4 - 7 + 19

= 3x² - 20x + 8.

Answer:

The value of n = 12

Step-by-step explanation:

Given the points

(-4, n)

(2, 4n)

The slope formula

m = y₂-y₁ / x₂ - x₁

$\left(x_1,\:y_1\right)=\left(-4,\:n\right),\:\left(x_2,\:y_2\right)=\left(2,\:4n\right)$

$m=\frac{4n-n}{2-\left(-4\right)}$

$m=\frac{n}{2}$

Given that the slope = m = 6

Thus, substituting the value

6 = n/2

n = 6 × 2

= 12

Thus, the value of n = 12

fgiga [73]

First break= 1/2
second break = 1/2 of half= 1/4
third break = half of 1/4 = 1/8
forth break = 1/2 of 1/8 = 1/16
fifth break = 1/2 of 1/16 =1/32
fraction painted = 1 -1/32 =31/32
portion painted = 150*31/32 = 145.3125 ft^2
