2a+54=38
2a=38-54
2a=-16
a=-16/2
a=-8
38 + 16 = 54
It is: 126 plus 54 = 180
2a^3 + 54 can first be factored into 2 (a^3 + 27). This can then be factored out to 2 (a + 3) (a^2 - 3a + 9).
Gle
54 + 560 + 90 = 704
93
54
346
The answer is 613.
if you are asking what y equals heres what it is y=54+4 y=58
405
