Cot(x)sec(x) =
(cos(x)/sin(x))(1/cos(x))=
cos(x)/(sin(x)cos(x)) =
1/sin(x) =

If that was the end and the question was "How many boxes did she sell?" then the answer is 6 boxes.
log(x+3)(2x+3)+log( x+3)( x+5) =2
logx(2x+3)+3(2x+3 )+log x(x+5)+3(x+5)

A) get rid of the fraction by finding the common denominator, 4. multiplying by 4 on both sides, I usually have it turned into a fraction, 4/1. The 2x=3/4, is now 8x=12/4 will be set as 8x=3. Divide 8, x=3/8.
B) The common denominator is 15. Multiply on both sides, -2/5 times 15/1 is -30/5 which becomes -6. And m/3 times 15/1 is 15m/3, 5m. divide the 5 and your answer is m=-5/6
Answer:
n = -7/5
Step-by-step explanation:
Let n = number
6n = (n+3) -10
Combine like terms
6n= n-7
Subtract n from each side
6n-n=n-n-7
5n = -7
Divide by 5 on each side
5n/5 = -7/5
n = -7/5
