Answer:
At these rates Sydney read 10 pages per hour more than Zander.
Step-by-step explanation:
Zander read
pages in
of an hour.
Therefore, pages read by Zander in 1 hour = ![\frac{\text{Total pages read}}{\text{Total time taken}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BTotal%20pages%20read%7D%7D%7B%5Ctext%7BTotal%20time%20taken%7D%7D)
= ![\frac{13\frac{3}{4}}{\frac{1}{4}}](https://tex.z-dn.net/?f=%5Cfrac%7B13%5Cfrac%7B3%7D%7B4%7D%7D%7B%5Cfrac%7B1%7D%7B4%7D%7D)
= ![\frac{55}{4}\times \frac{4}{1}](https://tex.z-dn.net/?f=%5Cfrac%7B55%7D%7B4%7D%5Ctimes%20%5Cfrac%7B4%7D%7B1%7D)
= 55 pages per hour
Sydney read
pages in
of an hours.
Pages read by Sydney in 1 hour = ![\frac{43\frac{1}{3}}{\frac{2}{3} }](https://tex.z-dn.net/?f=%5Cfrac%7B43%5Cfrac%7B1%7D%7B3%7D%7D%7B%5Cfrac%7B2%7D%7B3%7D%20%7D)
= ![\frac{130}{3}\times \frac{3}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B130%7D%7B3%7D%5Ctimes%20%5Cfrac%7B3%7D%7B2%7D)
= 65 pages per hour
Therefore, number of pages read more by Sydney as compared to Zander,
= 65 - 55
= 10 pages per hour
At these rates Sydney read 10 pages per hour more than Zander.

Answer:
3x³ - 12x + 4
Step-by-step explanation:
The opposite of a polynomial P is -P.
You find the opposite of P by multiplying it by -1.
P = -3x³ + 12x - 4
-P = (-1)( -3x³ + 12x - 4) Distribute -1 to each term
= (-1)(-3x³) + (-1)(12x) - (-1)(4) Multiply each coefficient by -1
= 3x³ + (-12)x - (-4)
= 3x³ - 12x + 4
