The answer is c.
Since a^2+b^2=c^2, b^2=c^2-a^2 thus,
16=4-b^2= srt. of 12
Answer:
B. 30
Step-by-step explanation:
the equation looks like 22 - x = -8 and 22 - 30 is negative 8
Calculate the number of hours between 4 PM and 10 AM:
4 PM to 4 AM is 12 hours.
4 AM to 10 AM is 6 hours
Total hours is 12 + 6 = 18 hours.
18 hours x 70 km/hr = 1,260 km total.
Y = -7
or
x = 10
or
y = x - 13
there can be endless answers
