Answer:
Id
I forget
Step-by-step explanation:
The given expression is in the form (a+b)(a-b) where
a = 5
b = sqrt(3)
Recall that
(a+b)(a-b) = a^2-b^2
is the difference of squares formula
If a = 5, then a^2 = 25
If b = sqrt(3), then b^2 = (sqrt(3))^2 = 3
The squaring undoes the square root. The two opposites cancel out.
So using a^2 = 25 and b^2 = 3, we can say
(a+b)(a-b) = a^2-b^2 = 25-3 = 22
Therefore,
(5+sqrt(3))(5-sqrt(3)) = 22
Answer: B) 22
Answer:
y = 2x + 5
Step-by-step explanation:
Answer:
The answer to the question is
it will take Dave 108.399 months or 9.03 years to reduce the balance to $0
Step-by-step explanation:
To solve the question, we note that
Balance cresdit = $20,000
APR = 20%
PMT = $400 per month we have
and
where r = 20 %÷12
P = $20000 and A = 400
Therefore we have
which gives 6/5=
= = 6 that is ln = ln (6) or n = = 108.399 months = 108.399/12 or 9.03 years
