Answer:
x = 135
Step-by-step explanation:
m = length of perpendicular line to hypotenuse
81/m = m/144
m² = 81 x 144 = 11664
m =√11664 = 108
Using the Pythagorean theorem:
x² = 81² + 108² = 6561 + 11664 = 18225
x = √18225 = 135
Answer:
(b² + 1) (b - 1)
Step-by-step explanation:
= b³ - b² + b - 1
= b² (b - 1) + 1(b - 1)
= (b² + 1) (b - 1)
Answer:
- a.
- b.
Step-by-step explanation:
a. 
b. 
<span>Thomas rented 2 bicycles, which were late for return by 6 days. His fine for being late was 18$. If the fine for being late is count by multiplying the number of bicycles with the duration of the late, the answer would be:
fine = number of bicycle * duration of late
$18 =fine rate* 2 bicyles * 6 days
fine rate= (($18/ 2 bicyles) / 6 days) = $0.66 /bicycle days</span>
C. because the 2nd number is 5 or up. Which makes it round up
