Combining the like terms, the simplified polynomials are given as follows:
a) 4x² - 14x + 17
b) -5x² - 20x + 8
<h3>How are polynomials simplified?</h3>
Polynomials are simplified combining the like terms, that is, adding these numbers with the same variable.
Item a:
4(x - 2)(x + 1) - 5(2x - 5)
Applying the distributive property:
4(x² - x - 2) - 10x + 25
4x² - 4x - 8 - 10x + 25
Combining the like terms:
4x² - 4x - 10x - 8 + 25
4x² - 14x + 17
Item b:
-5(x + 2)² + 28
-5(x² + 4x + 4) + 28
-5x² - 20x - 20 + 28
-5x² - 20x + 8

9,862,000 in scientific notation is 9.862 × 10^6
Answer:
35 percent of the 75,000 fans is: 0.35*75,000 = 26,250
since there are 2 fans per car we find the number of cars by dividing 26,250 by 2:
26,250 : 2 = 13,125 cars
5,000 will park at the stadium's parking lots, while the rest 13,125 - 5,000 = 8,125 cars will par at satellite lots.
OR
35% of 75000 = 26250
2 fans in a car
So, = 26250/2
= 13125
Total handling space = 5000
13125 - 5000 = 8125
