Answer:
(2n+6)(n+3)=
(2*n+2*3)(n+3)=
2(n+3)(n+3)=.....(1)
2(n+3)^2=....(2)
2(n^2+2*n*3+3^2) =
2(n^2+6n+9)=....(3)
2n^2+2*6n+2*9=
2n^2+12n+18.... (4)
15x3= - 3 =2
Step-by-step explanation:
and
By equating both equations, we get:
<em>[Separate variables and constants]</em>
By substituting to the above equation, we get:
Hence, and
x = 5
x/2 = 15/6
6 * x = 15 * 2
6x = 30
x = 30 / 6
