14000+7x=35x (x being the number of books) solve for x and you have your answer. 14000=35x-7x=28x therefore x=14000/28=500 so he needs to sell 500 books before he breaks even.
No solution but the equation is true
The answer is C.
SA = bh + (s1 + s2 + s3)H
SA = (6.8)(5.1) + (6.8 + 5.1 + 8.5)(2.5) = 85.68
Answer:
-sin(2A)
Step-by-step explanation:
1-(sin(A)+cons(A))^2
1-(sin(A)^2+2sin(A)cos(A)+cos(A)^2) :use FOIL to get it
1-(1+sin(2A))
1-1-sin(2A)
-sin(2A)
