It's A because of 162.75/.35
The answer would be 3 because you would count the amount of ‘x’s in the chart
<span>(1.3t3 + 0.4t2 – 24t) + (8 – 18t + 0.6t2)
In adding polynomials, make sure that each term is grouped together.
1.3t</span>³ + 0.4t² - 24t
<u> + 0.6t² - 18t + 8</u>
1.3t³ + 1.0t² - 42t + 8
In a polynomial equation, arrangement of each term is dependent on the exponential number. It should be from the highest exponent to the lowest.
