Answer:
D
Step-by-step explanation:
Given
(x - 5)³ = (x - 5)(x - 5)(x - 5)
Expand (x - 5)(x - 5) using FOIL then multiply the result by (x - 5)
(x - 5)(x - 5)
= x² - 5x - 5x + 25 = x² - 10x + 25, then
(x - 5)(x² - 10x + 25)
= x(x² - 10x + 25) - 5(x² - 10x + 25)
= x³ - 10x² + 25x - 5x² + 50x - 125 ← collect like terms
= x³ - 15x² + 75x - 125 → D
Answer: 111 dollars
Step-by-step explanation:
7 hours on Saturday and 4 hours on Sunday
Sunday gets paid 1 1/3, or 4/3 times more which is 9 x 4/3 = 12 per hour
Saturday is 9 per hour
7x9 (Saturday) + 4x12 (Sunday) = 111 dollars
We have to calculate how would it take for a red kangaroo to jump 2 km, if he jumps at a rate of 40 km/h.
Formula for the velocity is: v = d / t, where d stays for the distance and t stays for the time.
Therefore: t = d / v
t = 2 km / 40 km/h
t = 0.05 h = 3 minutes
Answer:
It would take 3 minutes.
