Answer: 20x4−24x3+20x2
Step-by-step explanation:
when simplifying you first distribute the -4x^2. This will result in -24x^3, 20x^4, and 20x^2
The maximum product is 42. Numbers 6 and 7 yield this product.
Answer:
a) From 10 to 11, Sarah rode 12 km in one hour. That means her velocity was 12 km/hr.
b) Sarah passed by her home at 12:45.
c) From 12 to 13, Sarah rode 15 km. Thus, her velocity was 15 km/hr. From 13 to 14 she rode 3 km. Thus, her velocity was 3 km/hr.
d) Her average velocity was 12+0+15+3/4, or 30/4 which is 7.5 km/hr.
