Lorie is using long division to find the quotient of 13 + 6r2 + 5 and 12 + 1 – 1, as shown. 41
+ 5 –
12 + - 1
I2 + 1 - 1) 1 3 + 612 + 0.1 + 5
(13 + 12 – 1
-
5.12 + I + 5
(5.12 + 51 – 5)
-4r + 0
What mistake did Lorie make?
ОА

ОС. .
She added an extra term to the dividend.
OD.

she combined the constants incorrectly in the last step i just got it right on the test

look at the step by step explanation for answer

step-by-step explanation:

d

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
