Answer:
x = -1/2 and -2
Step-by-step explanation:
Solve for <em>x</em>: Move all terms to the left side and set equal to zero. Then set each factor equal to zero.
Using the quadratic formula: Solve the equation for x by finding a, b, and c of the quadratic then applying the quadratic formula.

Answer:
xlog(64)−xlog(2)−2
Step-by-step explanation:
Simplify 6log(2) by moving 6 inside the logarithm.
log(2^6)x − log(2)x − 2
Raise 2 to the power of 6.
log(64)x − log(2)x − 2
Reorder factors in log(64)x − log(2)x −2.
Answer:
x > 367
Step-by-step explanation:
set x = # of DVDs they sold
Each DVD costs $15 so the total amount they made is 15x
Since they raised more than $5500
15x > 5500
Divide both sides by 15 to solve the inequality and you get
x > 366.67 and since you can't sell 0.67 of a DVD, round up to get
x > 367 which means that they sold more than 367 DVDs
