Answer 2
Answer: If Kiera's dance class starts at 4:30 p.m. and ends at 6:15 p.m. then how long is it? Lets find out. The way I solved it would be to count by hours. 4:30 to 5:30 is one hour. 5:30 to 6:30 is 2 hours. But 6:30 is too much time. So now you take away the required amount to make it 6:15. You have to take away 15 minutes. So 2 hours minus 15 equals 1 hour and 45 minutes. 
Kiera's dance class was 1 hour and 45 minutes long.

area = length x width

x² + 12x = l * x


A.  

First, you factor x from x² + 12x

x^(2) +12x=x(x+12)

area = x (x+12)

area = (x+12) * x

Length = x + 12



B.

If x = 10,
l = x + 12 = 10 +12 = 22
length = 22
and
Area = x² + 12x = 10² + 12(10) = 100 + 120 = 220
area = 220
