Answer:
k = 3, q = 9
Step-by-step explanation:
hmm.... what k will end up giving that 6x on the right side of the equation?
Since 6x is the second thingy in that expression, its a good idea to try dividing by 2, lets try k = 6/2 = 3!
(x+3)^2 = x^2+3x+3x+9
(x+3)^2 = x^2+6x+9
that fits pretty good!
So, k = 3, q = 9
Answer:
14x + 8
Explanation:
⇒ 4(5x+5) - 3(2x + 4)
distribute inside parenthesis
⇒ 4(5x) + 4(5) - 3(2x) - 3(4)
multiply the variables
⇒ 20x + 20 - 6x - 12
collect like terms
⇒ 20x - 6x + 20 - 12
subtract like term
⇒ 14x + 8

One class is 45 minutes.
That's 90 minutes per week.
8 weeks times 90 minutes is 720 minutes.
720 minutes divided by 60 minutes in the hour is 12 hours. Answer C.
