You divide 10 by 5 is two so 19 decided by five is 3.8
<h2><u>Polynomial Function</u></h2>
<h3>Evaluate the following function: Show all work! h(x)=3x²+2-2x, Find h(-2)</h3>
To determine the answer, substitute the given value to the function and simplify.
- h(x) = 3x² + 2 - 2x; h(-2)
- h(-2) = 3(-2)² + 2 - 2(-2)
- h(-2) = 3(4) + 2 + 4
- h(-2) = 12 + 2 + 4
- h(-2) = 14 + 4
- h(-2) = 18

The height of the triangle that forms the train track is 145,38 ft
<h3>How to calculate the height of the triangle?</h3>
To calculate the height of the triangle we must take into account the information provided by
- Base of the triangle = 1 mile = 5280 feet
- Railroad track expansion = 8 feet
According to the above, we must perform the following operations:
- 5280 ÷ 2 = 2640
- 8 ÷ 2 = 4
- 2640 + 4 = 2644
Subsequently, we must apply the Pythagorean theorem to find the height of the triangle having 2 data:
- Base: 2640ft
- Hypotenuse: 2644 ft
- 2644² = x² + 2640²
- x² = 2644² - 2640²
- x =
. - x =
![\sqrt[2]{21137}](https://tex.z-dn.net/?f=%5Csqrt%5B2%5D%7B21137%7D)
- x = 145,38 ft
That makes x approximately 145,38 ft.
