Step-by-step explanation:
25b * (3a² - 1) = 25b * 3a² - 25b * 1
= 75ba² - 25b
Distributive law upon subtraction:
a(x - y) = ax - ay
Answer:
take the population mean divided by four
Step-by-step explanation:
R+s-t-(r-s+t)
=2s-t is the answer
People think this answer would be just =2s but I have verified with an online calculator and the answer that textbooks look for regarding this is 2s-t
You would assume you would go r-r and thats 0 so no r's
you would say s-(-s) makes it plus and theres 2s
and you would say -t -(+t) is -t
that's why the answer is 2s-t
At first I also did t-(+t) and thought it would be no t's but the answer is in fact 2s-t

Answer:
x < -2 or 3 < x
Step-by-step explanation:
<u>6x -4 > 14</u>
6x > 18 . . . . add 4
x > 3 . . . . . . divide by 6
<u>3x +10 < 4</u>
3x < -6 . . . . subtract 10
x < -2 . . . . . divide by 3
The solution is the union of disjoint sets:
x < -2 or x > 3
