Hello from MrBillDoesMath!
Answer:
x = 0, +\-3
Discussion:
x^3 = 9x => subtract 9x from both sides
x^3 - 9x = 0 => factor x from both terms
x(x^2-9) = 0 => x = 0 or x^2 - 9 = 0
x = 0, +\-3
Thank you,
MrB
The simplified form of this polynomial is (n(20n + 1))/5
Answer:
length 60 feet
length 2=60 feet
width 1=30feet
width 2=30feet
those is because there is 4 sides to a rectangle
Step-by-step explanation:
because the length is twice the width, 2x 30=length
Answer:
$178.3
Step-by-step explanation:
The value of a car is $20,000
The car loses 10.7% of its value yearly
Since there are 12 months in a year then 10.7% can be represented as
10.7%/12
= 0.8916%
Therefore the approximate monthly decrease in value can be calculated as follows
= $20,000×0.8916/100
= $20,000×0.008916
= $178.3
Hence the approximate monthly decrease in value is $178.3
