Answer:-14
Step-by-step explanation:
(1-√-4)(-3-√-25)
[(1*-3)-(1*√-25)-(√-4*-3)-(√-4*√-25)]
(-3)-(-5)-(6)-(10)
-14
X=24
Work: x-10=14 x=14+10
7.5 mph in 3 hours the train can travel 22.5 miles. Take 2.5 and times it by 3 to get the mph, then multiply that answer by 3 again to get the total miles in 3 hours
First find the same denominator
15 30 45
6 12 18 24 30
The same denominator is 30.
What you do to the denominator you must do to the numerator.
So multiply
1/15 * 2/2 = 2/30
1/6 * 5/5 = 5/30
Then add
2/30 + 5/30 = 7/30
