There you !!!!! I hope this helped
Answer:
B
Step-by-step explanation:
So writing a polynomial in standard form is just combining all like terms and then rearranging those terms in descending order of degree. In this case, the term with the highest degree is 2x^2, then 3x, then -6, so our standard form polynomial is
Next, since there are three terms in this polynomial, this would be classified as a trinomial (tri = 3). Now to find the degree of this polynomial, just take the total number of exponents from the highest term, which in this case its 2x^2 with a total of 2. Putting it all together, this polynomial is a 2nd degree trinomial.
X=12.35
b = (2 × area)/a
= 5.63636
c = √ a2 + √ b2
= √112 + √ 5.63636363636362
= √152.76859504132
= 12.35996
Answer:4 runners finished the race
Step-by-step explanation:
There were 60 runners to start a race.
In the first half of the race, 2/3 of them dropped out. This means that the number of runners that dropped out would be
2/3 × 60 = 40 runners
The number of runners that is left out would be
60 - 40 = 20
In the second half of the race, 4/5 of the remaining runners dropped out. This means that the number of runners that dropped out would be
4/5 × 20 = 16 runners
Therefore the number of runners left and also finished the race would be
20 - 16 = 4
4 runners finished the race
