Answer:
1 hour 37 minutes
Step-by-step explanation:
From the image attached, we can see the start and end time represented by the clock. To calculate the length of time that Maria and her friends rode, we just have to subtract the start time from the end time.
From the end time clock, we can see that the end time is 2:24, while from the start time clock, we can see that the start time is 12:47. Hence, the length of time they rode is:
Length of time for bike ride = 2:24 - 12:47 = 1 hour 37 minutes

Answer:
84 yards squared
Step-by-step explanation:
Use the formula- A= 1/2(b1 +b2)h
So 8+6=14 and 14x12 equals 168. That times 1/2 equals 168 :)
Answer:
b,3 hours
Step-by-step explanation:
because you have 32 times 2 is 64 in 2 hours so that is not is so the times 8 is 256 in 8 hours so that is not it then times 16 is 512 so 512 in 16 hours that's not it so then times 3 it is 96 cars in 3 hours
Long way:
2(x-3)(x+3) = 2(x*x + 3*x - 3*x - 3*3)
2(x-3)(x+3) = 2(x^2 - 9)
2(x-3)(x+3) = 2x^2 - 2*9
2(x-3)(x+3) = 2x^2 - 18
Shortcut way:
Using formula (x+a)(x-a) = x^2 - a^2, where a = 3, in the case of (x+3)(x-3), so we have
(x+3)(x-3) = x^2 - 9.
Then, we multiply that by 2, which gives 2x^2 - 18.
