Answer:
<h2><u><em>
x = 25</em></u></h2>
Step-by-step explanation:
What is the solution to this equation?
6 * (x - 5) = 4x + 20
6x - 30 = 4x + 20
2x = 20 + 30
2x = 50
x = 50 : 2
x = 25
-------------------
check
6 * ( 25 - 5) = 4 * 25 + 20
6 * 20 = 100 + 20
120 = 120
the answer is good

Answer:
Step-by-step explanation:
plug in 3 , 5 and 17 for n
8 + 3(3 -1) = 8 + 6 = 14
8 + 3(5-1) = 8 + 12 = 20
8 + 3(17-1) = 8 + 48 = 56
Answer:
24m3−168m2+225m+30
Step-by-step explanation:
(3m+−6)(8m2+−40m+−5)
=(3m)(8m2)+(3m)(−40m)+(3m)(−5)+(−6)(8m2)+(−6)(−40m)+(−6)(−5)
=24m3−120m2−15m−48m2+240m+30
=24m3−168m2+225m+30
