Answer:
[tex]15 {g}^{2} + 15g[/tex]
Step-by-step explanation:
The given expresion is
[tex]3(5 {g}^{2} + 15g)[/tex]
when we expand this expression we get;
[tex]3(5 {g}^{2} + 15g) = 15 {g}^{2} + 45g [/tex]
Now let us analyze the options:
First:
[tex]15 {g}^{2} + 45g[/tex]
This is equivalent to the given expresion.
Second:
[tex]15({g}^{2} + 3g) = 15{g}^{2} + 45g[/tex]
Also equivalent
Third:
[tex]15g({g} + 3) = 15{g}^{2} + 45g[/tex]
Also equivalent
Fourth:
[tex]15 {g}^{2} + 15g \ne 15{g}^{2} + 45g[/tex]
Not equivalent
